DivRem
Rust library providing division and modulus variants:
- Floored division and remainder.
- Ceiled division and remainder.
- Euclidian division and remaider.
For every definition, we provide a Div
, a Rem
and a DivRem
trait.
A DivRem
variant of std
’s truncated division is also provided for convenience.
This crate is no_std
.

:
Division and modulus traits and implementations.
There are several definitions for the division and modulus
functions, each with different properties.
Probably the most common in computer science is truncated division
(rounding towards zero) since it is the one provided by most processors
and defined as the /
(and matching %
) operator in the ISO C99 standard.
This crate provides the following definitions:
- Floored division (rounding towards negative infinity).
- Ceiled division (rounding towards positive infinity).
- Euclidean division (sign of modulus is always positive).
For every definition, we provide a Div
, a Rem
and a DivRem
variant.
A DivRem
variant of the truncated division is also provided for
convenience since it does not exist in the standard library.
