mpmath

1.4.1 · active · verified Sat Mar 28

mpmath is a Python library for arbitrary-precision floating-point arithmetic, currently at version 1.4.1, with a release cadence of approximately every 1-2 years.

Warnings

gotcha Importing all functions with 'from mpmath import *' can lead to name conflicts with other libraries. It's recommended to import only the necessary functions or use the 'mpmath.' namespace.
Fix: Use explicit imports like 'from mpmath import mp, mpf' or access functions via 'mpmath.'
gotcha Mixing mpmath with other libraries that define functions with the same names can cause unexpected behavior. To avoid this, import only the needed functions or use the 'mpmath.' namespace.
Fix: Use explicit imports or access functions via 'mpmath.'

Install

pip install mpmath Install mpmath

Imports

mp
```
from mpmath import mp
```
Importing the 'mp' context object allows setting the precision for arithmetic operations.
mpf
```
from mpmath import mpf
```
Importing 'mpf' enables the creation of arbitrary-precision floating-point numbers.

Quickstart

This example computes 50 digits of pi by numerically evaluating the Gaussian integral using mpmath.

from mpmath import mp
mp.dps = 50
print(mp.quad(lambda x: mp.exp(-x**2), [-mp.inf, mp.inf]) ** 2)
