TL;DR

PEP 485 introduced math.isclose() to solve the fundamental problem of comparing floating-point numbers by testing if two values are “approximately equal” rather than exactly equal.

TL;DR

The statistics module provides mathematical statistics functions for calculating averages, spread measures, and correlations without external dependencies.

Interesting!

Unlike floating-point calculations, the statistics module can work with Decimal and Fraction types for exact mathematical precision in statistical calculations!
