◆ arg
Callable object computing the phase angle (in radians). Required header: Members Functions
template<floating_value T> auto operator()(T x) const noexcept;
Parameters
Return value For each element of the input the phase angle is returned: If the input type is a floating real value:
auto operator[]( conditional_expression auto cond ) const noexcept;
Higher-order function generating a masked version of eve::arg Parameters
Return value A Callable object so that the expression Supported decorators
