A package providing a fraction-based Real class that allows you to do exact real arithmetic, along with some algorithms
Project description
This is a Python package to do exact real arithmetic, the following is an example using it:
from precreal import Real,intpow,pi
>>> 0.1+0.2==0.3 # Precision loss
False
>>> Real("0.1")+Real("0.2")==Real("0.3") # The Real class has NO precision loss when doing arithmetic
True
>>> intpow(Real(2),100)
1267650600228229401496703205376
>>> pi(7)
3.1415926
You can also run precreal_test, which tests three features of this package.
