Not combining `hfsq` with `R` also keeps `R` small (though not as small as a true `lo` term would be), so that extra precision is not needed for terms involving `R`.\n\t* - When implemented in C, compiler bugs involving extra precision used to break Dekker's theorem for spitting `f-hfsq` as `hi+lo`. These problems are now automatically avoided as a side effect of the optimization of combining the Dekker splitting step with the clear-low-bits step.\n\t* - `y` must (for args near `sqrt(2)` and `1/sqrt(2)`) be added in extra precision to avoid a very large cancellation when `x` is very near these values. Unlike the above cancellations, this problem is specific to base `2`. It is strange that adding `+-1` is so much harder than adding `+-ln2` or `+-log10_2`.\n\t* - This implementation uses Dekker's theorem to normalize `y+val_hi`, so, when implemented in C, compiler bugs may reappear in some configurations.\n\t* - The multi-precision calculations for the multiplications are routine.\n\t*/\n\thi = f - hfsq;\n\thi = setLowWord( hi, 0 );\n\tlo = ( f - hi ) - hfsq + R;\n\tvalHi = hi * IVLN2HI;\n\tvalLo = ( ( lo + hi ) * IVLN2LO ) + ( lo * IVLN2HI );\n\n\tw = y + valHi;\n\tvalLo += ( y - w ) + valHi;\n\tvalHi = w;\n\n\treturn valLo + valHi;\n}\n\n\n// EXPORTS //\n\nexport default log2;\n","/**\n* @license Apache-2.0\n*\n* Copyright (c) 2018 The Stdlib Authors.\n*\n* Licensed under the Apache License, Version 2.0 (the \"License\");\n* you may not use this file except in compliance with the License.\n* You may obtain a copy of the License at\n*\n* http://www.apache.org/licenses/LICENSE-2.0\n*\n* Unless required by applicable law or agreed to in writing, software\n* distributed under the License is distributed on an \"AS IS\" BASIS,\n* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n* See the License for the specific language governing permissions and\n* limitations under the License.\n*/\n\n'use strict';\n\n// MODULES //\n\nimport isnan from '@stdlib/math-base-assert-is-nan';\nimport isInfinite from '@stdlib/math-base-assert-is-infinite';\nimport pow from '@stdlib/math-base-special-pow';\nimport floor from '@stdlib/math-base-special-floor';\nimport ceil from '@stdlib/math-base-special-ceil';\nimport log2 from '@stdlib/math-base-special-log2';\nimport MAX_EXP from '@stdlib/constants-float64-max-base2-exponent';\nimport MIN_EXP_SUBNORMAL from '@stdlib/constants-float64-min-base2-exponent-subnormal';\nimport PINF from '@stdlib/constants-float64-pinf';\n\n\n// MAIN //\n\n/**\n* Rounds a numeric value to the nearest power of two toward positive infinity.\n*\n* @param {number} x - input value\n* @returns {number} rounded value\n*\n* @example\n* var v = ceil2( 3.141592653589793 );\n* // returns 4.0\n*\n* @example\n* var v = ceil2( 9.0 );\n* // returns 16.0\n*\n* @example\n* var v = ceil2( -0.314 );\n* // returns -0.25\n*/\nfunction ceil2( x ) {\n\tvar sign;\n\tvar p;\n\tif (\n\t\tisnan( x ) ||\n\t\tisInfinite( x ) ||\n\t\tx === 0.0\n\t) {\n\t\treturn x;\n\t}\n\tif ( x < 0 ) {\n\t\tx = -x;\n\t\tsign = -1.0;\n\t} else {\n\t\tsign = 1.0;\n\t}\n\t// Solve the equation `2^p = x` for `p`:\n\tp = log2( x );\n\n\t// If provided the smallest subnormal, no rounding possible:\n\tif ( p === MIN_EXP_SUBNORMAL ) {\n\t\treturn x;\n\t}\n\t// Determine a power of two which rounds the input value toward positive infinity:\n\tif ( sign === -1.0 ) {\n\t\tp = floor( p );\n\t} else {\n\t\tp = ceil( p );\n\t}\n\t// Handle overflow:\n\tif ( p > MAX_EXP ) {\n\t\treturn PINF;\n\t}\n\treturn sign * pow( 2.0, p );\n}\n\n\n// EXPORTS //\n\nexport default ceil2;\n","/**\n* @license Apache-2.0\n*\n* Copyright (c) 2024 The Stdlib Authors.\n*\n* Licensed under the Apache License, Version 2.0 (the \"License\");\n* you may not use this file except in compliance with the License.\n* You may obtain a copy of the License at\n*\n* http://www.apache.org/licenses/LICENSE-2.0\n*\n* Unless required by applicable law or agreed to in writing, software\n* distributed under the License is distributed on an \"AS IS\" BASIS,\n* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n* See the License for the specific language governing permissions and\n* limitations under the License.\n*\n*\n* ## Notice\n*\n* The following copyright and license were part of the original implementation available as part of [FreeBSD]{@link https://svnweb.freebsd.org/base/release/12.2.0/lib/msun/src/k_log.h}.

To do so, we allocate a new `ArrayBuffer` in a manner similar to how `Arrays` are resized (i.e., allocate enough memory to hold `nextpow2(n)` elements).\n* - Beware that, if an ArrayBuffer view is preceded by one or more other views, the created view may contain elements from those views, thus resulting in possible mutation. Accordingly, providing a typed array view having a shared underlying `ArrayBuffer` may have unintended consequences (including security vulnerabilities).\n*\n* @private\n* @param {TypedArray} arr - input array\n* @param {ArrayLike} items - items to add\n* @returns {TypedArray} input array\n*\n* @example\n* var Float64Array = require( '@stdlib/array-float64' );\n*\n* var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );\n* // returns [ 1.0, 2.0, 3.0, 4.0, 5.0 ]\n*\n* arr = prepend( arr, [ 6.0, 7.0 ] );\n* // returns [ 6.0, 7.0, 1.0, 2.0, 3.0, 4.0, 5.0 ]\n*/\nfunction prepend( arr, items ) {\n\tvar nbytes;\n\tvar ibytes;\n\tvar offset;\n\tvar total;\n\tvar len;\n\tvar buf;\n\tvar n;\n\tvar v;\n\tvar i;\n\n\tlen = arr.length;\n\tn = items.length;\n\n\tibytes = n * arr.BYTES_PER_ELEMENT;\n\toffset = arr.byteOffset;\n\n\tif ( offset < ibytes ) {\n\t\tnbytes = len * arr.BYTES_PER_ELEMENT;\n\t\ttotal = nbytes + ibytes + offset;\n\t\tbuf = new ArrayBuffer( ceil2( total+1 ) );\n\t\toffset = buf.byteLength - nbytes - ibytes;\n\t\tv = new arr.constructor( buf, offset, len+n );\n\t\tfor ( i = 0; i < len; i++ ) {\n\t\t\tv[ i+n ] = arr[ i ];\n\t\t}\n\t} else {\n\t\toffset -= ibytes;\n\t\tv = new arr.constructor( arr.buffer, offset, len+n );\n\t}\n\tfor ( i = 0; i < n; i++ ) {\n\t\tv[ i ] = items[ i ];\n\t}\n\treturn v;\n}\n\n\n// EXPORTS //\n\nmodule.exports = prepend;\n", "/**\n* @license Apache-2.0\n*\n* Copyright (c) 2018 The Stdlib Authors.\n*\n* Licensed under the Apache License, Version 2.0 (the \"License\");\n* you may not use this file except in compliance with the License.\n* You may obtain a copy of the License at\n*\n* http://www.apache.org/licenses/LICENSE-2.0\n*\n* Unless required by applicable law or agreed to in writing, software\n* distributed under the License is distributed on an \"AS IS\" BASIS,\n* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n* See the License for the specific language governing permissions and\n* limitations under the License.\n*/\n\n'use strict';\n\n// MODULES //\n\nvar isArray = require( '@stdlib/assert-is-array' );\nvar isCollection = require( '@stdlib/assert-is-collection' );\nvar isTypedArrayLike = require( '@stdlib/assert-is-typed-array-like' );\nvar isInteger = require( '@stdlib/assert-is-integer' );\nvar format = require( '@stdlib/string-format' );\nvar prependArray = require( './prepend_array.js' );\nvar prependObject = require( './prepend_object.js' );\nvar prependTypedArray = require( './prepend_typed_array.js' );\n\n\n// MAIN //\n\n/**\n* Adds elements from one collection to the beginning of another collection.\n*\n* @param {Collection} collection1 - collection\n* @param {Collection} collection2 - collection containing elements to add\n* @throws {TypeError} first argument must be either an array, typed array, or an array-like object\n* @throws {TypeError} second argument must be an array-like object\n* @returns {Collection} updated collection\n*\n* @example\n* var arr = [ 1.0, 2.0, 3.0, 4.0, 5.0 ];\n*\n* arr = prepend( arr, [ 6.0, 7.0 ] );\n* // returns [ 6.0, 7.0, 1.0, 2.0, 3.0, 4.0, 5.0 ]\n*\n* @example\n* var Float64Array = require( '@stdlib/array-float64' );\n*\n* var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );\n* // returns [ 1.0, 2.0, 3.0, 4.0, 5.0 ]\n*\n* arr = prepend( arr, [ 6.0, 7.0 ] );\n* // returns [ 6.0, 7.0, 1.0, 2.0, 3.0, 4.0, 5.0 ]\n*/\nfunction prepend( collection1, collection2 ) {\n\tif ( !isCollection( collection2 ) ) {\n\t\tthrow new TypeError( format( 'invalid argument.

Not combining `hfsq` with `R` also keeps `R` small (though not as small as a true `lo` term would be), so that extra precision is not needed for terms involving `R`.\n\t* - When implemented in C, compiler bugs involving extra precision used to break Dekker's theorem for spitting `f-hfsq` as `hi+lo`. These problems are now automatically avoided as a side effect of the optimization of combining the Dekker splitting step with the clear-low-bits step.\n\t* - `y` must (for args near `sqrt(2)` and `1/sqrt(2)`) be added in extra precision to avoid a very large cancellation when `x` is very near these values. Unlike the above cancellations, this problem is specific to base `2`. It is strange that adding `+-1` is so much harder than adding `+-ln2` or `+-log10_2`.\n\t* - This implementation uses Dekker's theorem to normalize `y+val_hi`, so, when implemented in C, compiler bugs may reappear in some configurations.\n\t* - The multi-precision calculations for the multiplications are routine.\n\t*/\n\thi = f - hfsq;\n\thi = setLowWord( hi, 0 );\n\tlo = ( f - hi ) - hfsq + R;\n\tvalHi = hi * IVLN2HI;\n\tvalLo = ( ( lo + hi ) * IVLN2LO ) + ( lo * IVLN2HI );\n\n\tw = y + valHi;\n\tvalLo += ( y - w ) + valHi;\n\tvalHi = w;\n\n\treturn valLo + valHi;\n}\n\n\n// EXPORTS //\n\nexport default log2;\n","/**\n* @license Apache-2.0\n*\n* Copyright (c) 2018 The Stdlib Authors.\n*\n* Licensed under the Apache License, Version 2.0 (the \"License\");\n* you may not use this file except in compliance with the License.\n* You may obtain a copy of the License at\n*\n* http://www.apache.org/licenses/LICENSE-2.0\n*\n* Unless required by applicable law or agreed to in writing, software\n* distributed under the License is distributed on an \"AS IS\" BASIS,\n* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n* See the License for the specific language governing permissions and\n* limitations under the License.\n*/\n\n'use strict';\n\n// MODULES //\n\nimport isnan from '@stdlib/math-base-assert-is-nan';\nimport isInfinite from '@stdlib/math-base-assert-is-infinite';\nimport pow from '@stdlib/math-base-special-pow';\nimport floor from '@stdlib/math-base-special-floor';\nimport ceil from '@stdlib/math-base-special-ceil';\nimport log2 from '@stdlib/math-base-special-log2';\nimport MAX_EXP from '@stdlib/constants-float64-max-base2-exponent';\nimport MIN_EXP_SUBNORMAL from '@stdlib/constants-float64-min-base2-exponent-subnormal';\nimport PINF from '@stdlib/constants-float64-pinf';\n\n\n// MAIN //\n\n/**\n* Rounds a numeric value to the nearest power of two toward positive infinity.\n*\n* @param {number} x - input value\n* @returns {number} rounded value\n*\n* @example\n* var v = ceil2( 3.141592653589793 );\n* // returns 4.0\n*\n* @example\n* var v = ceil2( 9.0 );\n* // returns 16.0\n*\n* @example\n* var v = ceil2( -0.314 );\n* // returns -0.25\n*/\nfunction ceil2( x ) {\n\tvar sign;\n\tvar p;\n\tif (\n\t\tisnan( x ) ||\n\t\tisInfinite( x ) ||\n\t\tx === 0.0\n\t) {\n\t\treturn x;\n\t}\n\tif ( x < 0 ) {\n\t\tx = -x;\n\t\tsign = -1.0;\n\t} else {\n\t\tsign = 1.0;\n\t}\n\t// Solve the equation `2^p = x` for `p`:\n\tp = log2( x );\n\n\t// If provided the smallest subnormal, no rounding possible:\n\tif ( p === MIN_EXP_SUBNORMAL ) {\n\t\treturn x;\n\t}\n\t// Determine a power of two which rounds the input value toward positive infinity:\n\tif ( sign === -1.0 ) {\n\t\tp = floor( p );\n\t} else {\n\t\tp = ceil( p );\n\t}\n\t// Handle overflow:\n\tif ( p > MAX_EXP ) {\n\t\treturn PINF;\n\t}\n\treturn sign * pow( 2.0, p );\n}\n\n\n// EXPORTS //\n\nexport default ceil2;\n","/**\n* @license Apache-2.0\n*\n* Copyright (c) 2024 The Stdlib Authors.\n*\n* Licensed under the Apache License, Version 2.0 (the \"License\");\n* you may not use this file except in compliance with the License.\n* You may obtain a copy of the License at\n*\n* http://www.apache.org/licenses/LICENSE-2.0\n*\n* Unless required by applicable law or agreed to in writing, software\n* distributed under the License is distributed on an \"AS IS\" BASIS,\n* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n* See the License for the specific language governing permissions and\n* limitations under the License.\n*\n*\n* ## Notice\n*\n* The following copyright and license were part of the original implementation available as part of [FreeBSD]{@link https://svnweb.freebsd.org/base/release/12.2.0/lib/msun/src/k_log.h}.
