xieite::abs()

Defined in header <xieite/math/abs.hpp>

Computes the absolute of a value.
If the value's type is a signed integer, returns the corresponding unsigned integer type, otherwise uses std::abs() for floating-point types.


Declaration

 
template<xieite::is_arith T>
[[nodiscard]] constexpr xieite::try_unsigned<T> abs(T value) noexcept;


Example

 
int main() {
	std::int8_t x = std::numeric_limits<std::int8_t>::min();

	xieite::dump(x);
	xieite::dump(xieite::abs(x));
}
