Defined in header <chrono>
template <class Rep, class Period> constexpr duration<Rep, Period> abs(duration<Rep, Period> d)		(since C++17)

Returns the absolute value of the duration d. Specifically, if d >= d.zero(), return d, otherwise return -d.

The function does not participate in the overload resolution unless std::numeric_limits<Rep>::is_signed is true.

Parameters

d

-

duration

Return value

Absolute value of d

Possible implementation

template <class Rep, class Period, class = std::enable_if_t< std::chrono::duration<Rep, Period>::min() < std::chrono::duration<Rep, Period>::zero()>> constexpr std::chrono::duration<Rep, Period> abs(duration<Rep, Period> d) { return d >= d.zero() ? d : -d; }
