◆ cbrt

eve::cbrt = {}
inlineconstexpr

Callable object computing the cubic root.

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

Members Functions

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

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

Parameters

x: floating real value.

Return value

Returns the elementwise cubic root value of the input.


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

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

Parameters

cond : conditional expression

Return value

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