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
CheckedAdd	Performs addition that returns None instead of wrapping around on overflow.
CheckedDiv	Performs division that returns None instead of panicking on division by zero and instead of wrapping around on underflow and overflow.
CheckedMul	Performs multiplication that returns None instead of wrapping around on underflow or overflow.
CheckedShl	Performs a left shift that returns None on shifts larger than the type width.
CheckedShr	Performs a right shift that returns None on shifts larger than the type width.
CheckedSub	Performs subtraction that returns None instead of wrapping around on underflow.
Float	Generic trait for floating point numbers
FloatConst
FromPrimitive	A generic trait for converting a number to a value.
Num	The base trait for numeric types, covering 0 and 1 values, comparisons, basic numeric operations, and string conversion.
NumAssign	The trait for Num types which also implement assignment operators.
NumAssignOps	The trait for types implementing numeric assignment operators (like +=).
NumAssignRef	The trait for NumAssign types which also implement assignment operations taking the second operand by reference.
NumCast	An interface for casting between machine scalars.
NumOps	The trait for types implementing basic numeric operations
NumRef	The trait for Num types which also implement numeric operations taking the second operand by reference.
One	Defines a multiplicative identity element for Self.
PrimInt	Generic trait for primitive integers.
RefNum	The trait for references which implement numeric operations, taking the second operand either by value or by reference.
Saturating	Saturating math operations
Signed	Useful functions for signed numbers (i.e. numbers that can be negative).
ToPrimitive	A generic trait for converting a value to a number.
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.
WrappingSub	Performs subtraction that wraps around on overflow.
Zero	Defines an additive identity element for Self.

Functions

abs	Computes the absolute value.
abs_sub	The positive difference of two numbers.
cast	Cast from one machine scalar to another.
checked_pow	Raises a value to the power of exp, returning None if an overflow occurred.
clamp	A value bounded by a minimum and a maximum
one	Returns the multiplicative identity, 1.
pow	Raises a value to the power of exp, using exponentiation by squaring.
signum	Returns the sign of the number.
zero	Returns the additive identity, 0.
