Fixed

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

Note: When converting a fixed-precision number to a floating point number, they may not be exact bit-for-bit equal; as such an approximate equals operation is recommended for comparing fixed point math with

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

) if (

__traits(isIntegral, T) &&

!__traits(isUnsigned, T)
