What is the easiest way to calculate extremely precise?

I would like to compute my calculations as precise as possible, does anyone know a way to get much more preciese answers? Thank you very much.

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')
