◆ conj

eve::conj = {}
inlineconstexpr

Callable object computing the conjugate value.

Required header: #include <eve/function/conj.hpp>

Members Functions

Member Effect
operator() the computation of the conjugate value
operator[] Construct a conditional version of current function object

auto operator()(floating_value auto x ) const noexcept;
Definition: value.hpp:83

Parameters

x: the floating value to conjugate

Return value

This function acts as identity on real entries


auto operator[]( conditional_expression auto cond ) const noexcept;

Higher-order function generating a masked version of eve::conj

Parameters

cond : conditional expression

Return value

A Callable object so that the expression conj[cond](x, ...) is equivalent to if_else(cond,conj(x, ...),x)
