Hi! I've noticed a bug related to the rounding function.

Heads up: I'm quite confident that this is the same bug as described here: adafruit/circuitpython#1890.

Board/system information:

(sysname='GPy', nodename='GPy', release='1.20.2.r6', version='v1.11-c5a0a97 on 2021-10-28', machine='GPy with ESP32', pybytes='1.7.1')

Bug report

Rounding integer values with a custom number of decimals seems to throw a NotImplementedError:

>>> round(1, 2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NotImplementedError:

If the values is converted to float, it works fine:

>>> round(float(1), 2)
1.0
