Functions
-
template<typename T, <SFINAE> = 0>auto dip::
saturated_add(T lhs, T rhs) -> T constexpr - Adds two values using saturated arithmetic.
-
template<typename T, <SFINAE> = 0>auto dip::
saturated_sub(T lhs, T rhs) -> T constexpr - Subtracts two values using saturated arithmetic.
-
template<typename T, <SFINAE> = 0>auto dip::
saturated_mul(T lhs, T rhs) -> T constexpr - Multiplies two values using saturated arithmetic.
-
template<typename T, <SFINAE> = 0>auto dip::
saturated_div(T lhs, T rhs) -> T constexpr - Divides two values using saturated arithmetic.
-
template<typename T>auto dip::
saturated_safediv(T lhs, T rhs) -> T constexpr - Divides two values using saturated arithmetic. Tests for division by zero, return 0 rather than infinity or NaN (or an exception).
-
template<typename T, <SFINAE> = 0>auto dip::
saturated_inv(T v) -> T constexpr - Inverts a value using saturated arithmetic. This is the same as negation, but not for unsigned values.
