modf

Description

Split into integer and fractional parts (both with same sign).

Signature

T modf<T>(
    T x,
    out T ip)
    where T : __BuiltinFloatingPointType;

vector<T, N> modf<T, N:int>(
    vector<T, N> x,
    out vector<T, N> ip)
    where T : __BuiltinFloatingPointType;

matrix<T, N, M> modf<T, N:int, M:int, L:int>(
    matrix<T, N, M> x,
    out matrix<T, N, M> ip)
    where T : __BuiltinFloatingPointType;
