Enums

isFixed

eponymoustemplate isFixed(T)

Gets whether the provided value is a instance of Fixed

Functions

ceil

T ceil(T x)

Computes the nearest integer value greater than the given value.

floor

T floor(T x)

Computes the nearest integer value lower than the given value.

fract

T fract(T value)

Gets the fractional part of the value.

trunc

T trunc(T x)

Computes the nearest integer value lower in magnitude than the given value.

Structs

Fixed

struct Fixed(T, size_t FRACT_BITS = (8 * (T.sizeof / 2)))

Fixed-point math type, fractional bits can be specified, but by default is split evenly; eg Fixed!int will be Q16.16
