# `ieee754`

[![Build Status](https://travis-ci.org/huonw/ieee754.svg?branch=master)](https://travis-ci.org/huonw/ieee754) [![codecov](https://codecov.io/gh/huonw/ieee754/branch/master/graph/badge.svg)](https://codecov.io/gh/huonw/ieee754)

Low-level manipulations of IEEE754 floating-point numbers.

This library includes:

- `no_std` support by default,

- ulp computation (units in the last place, representing the resolution of a

  float),

- miscellaneous functions like `nextafter` (`next` and `prev`),

  `copysign` (`copy_sign`), `abs`, `sign`,

- the IEEE-754 `totalOrder` predicate for doing `Ord::cmp`-like

  comparisons on floats,

- an iterator over every floating point value in a range,

- a parallel iterator over every floating point value in a range

  (optional: activate with the `rayon` feature),

- relative error computation.
