wrap()

template<typename T >

T MayaFlux::Kinesis::wrap ( T  x, T  lo, T  hi  )

inlinenoexcept

Wrap x into [lo, hi) with modulo semantics.

Unlike std::fmod, handles negative values and arbitrary lo correctly. Equivalent to the GLSL mod() applied after shifting by lo.

Example: wrap(-0.1F, 0.F, 1.F) -> 0.9F

Definition at line 218 of file Scalar.hpp.

{
    const T range = hi - lo;
    if (range <= T { 0 })
        return lo;
    return x - range * std::floor((x - lo) / range);
}
