Saturated arithmetics functions

satadd function

template <typename T1, typename T2,
          KFR_ENABLE_IF(is_numeric_args<T1, T2>),
          typename Tout = std::common_type_t<T1, T2>>
Tout satadd(const T1 &x, const T2 &y)

Adds two arguments using saturation

Source code

template <typename T1, typename T2, KFR_ENABLE_IF(is_numeric_args<T1, T2>),
          typename Tout = std::common_type_t<T1, T2>>
KFR_INTRINSIC Tout satadd(const T1& x, const T2& y)
{
    return intrinsics::satadd(x, y);
}

satsub function

template <typename T1, typename T2,
          KFR_ENABLE_IF(is_numeric_args<T1, T2>),
          typename Tout = std::common_type_t<T1, T2>>
Tout satsub(const T1 &x, const T2 &y)

Subtracts two arguments using saturation

Source code

template <typename T1, typename T2, KFR_ENABLE_IF(is_numeric_args<T1, T2>),
          typename Tout = std::common_type_t<T1, T2>>
KFR_INTRINSIC Tout satsub(const T1& x, const T2& y)
{
    return intrinsics::satsub(x, y);
