What is the easiest way to calculate extremely precise?

Question

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.

Answer 1

You can use decimal module

from decimal import Decimal, getcontext

getcontext().prec = 100
print(Decimal('2') ** Decimal('.5'))

Answer 2

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.

Answer 3

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

Answer 4

believe me or not,

only way to do this is only practising and more practising maths calculations as much difficult as possible

Answer 5

I mean in python...
