how to prevent rounding my number automatically in python3

Question

am want to divide 99999999999999999 on 100000 the answer is 9999999.9999999999‬ but python is auto rounding it to 1000000000000.0

>>> 99999999999999999/100000
1000000000000.0

This is not (just) Python, this is [floating point](https://en.wikipedia.org/wiki/Double-precision_floating-point_format) math. — Boris Verkhovskiy, Oct 18 '19 at 03:16

Use Decimal

>>> from decimal import Decimal
>>> Decimal(99999999999999999)/Decimal(100000)
Decimal('999999999999.99999')
