You can use decimal module
from decimal import Decimal, getcontext
getcontext().prec = 100
print(Decimal('2') ** Decimal('.5'))

With sympy module, you can use rational numbers, that is you can calculate with 3/7 or 31/32 etc without actually forcing the computer to round to a floating point precision.

Can you post your code?
It returns 0.333... for both Decimal(1) / Decimal(3) and Decimal('1') / Decimal('3')
