    T x,
    out int exp)
    where T : __BuiltinFloatingPointType;

vector<T, N> frexp<T, N:int>(
    vector<T, N> x,
    out vector<int, N> exp)
    where T : __BuiltinFloatingPointType;

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