Division and modulus traits and implementations.
There exist many possible definitions of 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 other 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
Rem and a
DivRem variant of the truncated division is also provided for
convenience since it does not exist in the standard library.
