Module num 

Additional functionality for numerics.

This module provides traits that are useful when doing numerical work. See the individual documentation for each piece for more information.

Traits

AsPrimitive

A generic interface for casting between machine scalars with the as operator, which admits narrowing and precision loss. Implementers of this trait AsPrimitive should behave like a primitive numeric type (e.g. a newtype around another primitive), and the intended conversion must never fail.

Bounded

Numbers which have upper and lower bounds

NonZero

Functions for primitive type, which has a non-zero correspondant.

Num

The base trait for numeric types, covering 0 and 1 values, comparisons, basic numeric operations, and string conversion.

NumCast

An interface for casting between machine scalars.

NumOps

Generic trait for types implementing basic numeric operations

One

Defines a multiplicative identity element for Self.

PrimInt

Generic trait for primitive integers.

PrimUnsignedInt

Functions for primitive unsigned integral types.

Saturating

Saturating math operations. Deprecated, use SaturatingAdd, SaturatingSub and SaturatingMul instead.

Signed

Useful functions for signed numbers (i.e. numbers that can be negative).

Unsigned

A trait for values which cannot be negative

WrappingAdd

Performs addition that wraps around on overflow.

WrappingMul

Performs multiplication that wraps around on overflow.

WrappingShl

Performs a left shift that does not panic.

WrappingShr

Performs a right shift that does not panic.

WrappingSub

Performs subtraction that wraps around on overflow.

Zero

Defines an additive identity element for Self.
