# Constant tau

## Summary

Implement a constant `math.tau` to hold the tau constant.

## Motivation

Currently the value of tau is used in trigonomic calculations through `math.pi * 2`.

The implementation of tau will simplify equations where otherwise math.pi * 2 may be used.

## Design

Define `math.tau` with the value `6.28318530717958647692528676655900577`

## Drawbacks

None
