Description

Utilities for calculating floating point constants in const context.

This package is not intended heavy numerical calculation but just evaluating floating point constants in const contest.

Usage

use ::const_frac::Frac;

const RAD2DEG: f64 = Frac::from_ratio(360, 2, 0).mul(Frac::from_exp_pi(-1)).to_f64();

assert_eq!(RAD2DEG * std::f64::consts::PI, 180f64);

Features

This package has the following feature flags. No feature flags are enabled by default.

• std Enable std support.
• tokenize Enable Parse and ToToken implementation for Frac when using in implementation of a procedural macro.
• ratio Enable num_rational::BigRational supports.

Project status

This package is in the very early stage.
