+There seems to be a number that fulfills all of these conditions:
+
+```
+  i * i = 0
+  i + 1 = 1
+  i - 1 = -1
+  i / i = 1
+```
+
+Turns out that this magical number is not even an integer:
+
+```
+  i = Number.MIN_VALUE
+```
+
+It's the smallest possible fraction JavaScript can produce, and is treated as zero for the most part.
+
+Conversely, the largest possible fraction claims to be greater than one, but reduces to zero:
+
+```
+  i = Number.MAX_VALUE
+
+  i > 1 // true
+  i|0   // 0
+```
+
+Furthermore, both the largest possible fraction and integer refuse to wrap around:
+
+```
+  i = Number.MAX_VALUE
+  j = 0xffffffffffffffff
+
+  i === (i + 1) // true
+  j === (j + 1) // true
+```
