Numeric traits and functions for generic mathematics

Enums

Used for representing the classification of floating point numbers

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 wrapping around on underflow or overflow.
CheckedMul	Performs multiplication that returns `None` instead of wrapping around on underflow or overflow.
CheckedSub	Performs subtraction that returns `None` instead of wrapping around on underflow.
Float	Operations on primitive floating point numbers.
FromPrimitive	A generic trait for converting a number to a value.
Int	A primitive signed or unsigned integer equipped with various bitwise operators, bit counting methods, and endian conversion functions.
Num	The base trait for numeric types
NumCast	An interface for casting between machine scalars.
One	Defines a multiplicative identity element for `Self`.
Primitive	Specifies the available operations common to all of Rust's core numeric primitives. These may not always make sense from a purely mathematical point of view, but may be useful for systems programming.
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
Zero	Defines an additive identity element for `Self`.

abs	Computes the absolute value.
abs_sub	The positive difference of two numbers.
cast	Cast from one machine scalar to another.
checked_next_power_of_two	Returns the smallest power of 2 greater than or equal to `n`. If the next power of two is greater than the type's maximum value, `None` is returned, otherwise the power of 2 is wrapped in `Some`.
div_rem	Simultaneous division and remainder
from_f32	A utility function that just calls `FromPrimitive::from_f32`.
from_f64	A utility function that just calls `FromPrimitive::from_f64`.
from_i16	A utility function that just calls `FromPrimitive::from_i16`.
from_i32	A utility function that just calls `FromPrimitive::from_i32`.
from_i64	A utility function that just calls `FromPrimitive::from_i64`.
from_i8	A utility function that just calls `FromPrimitive::from_i8`.
from_int	A utility function that just calls `FromPrimitive::from_int`.
from_u16	A utility function that just calls `FromPrimitive::from_u16`.
from_u32	A utility function that just calls `FromPrimitive::from_u32`.
from_u64	A utility function that just calls `FromPrimitive::from_u64`.
from_u8	A utility function that just calls `FromPrimitive::from_u8`.
from_uint	A utility function that just calls `FromPrimitive::from_uint`.
is_power_of_two
next_power_of_two	Returns the smallest power of 2 greater than or equal to `n`.
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`.
