◆ is_nlez

eve::is_nlez = {}
inlineconstexpr

Callable object computing the "not less or equal to zero" predicate.

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

Members Functions

Member Effect
operator() the "not less or equal to zero" predicate
operator[] Construct a conditional version of current function object

auto operator()(value x) const noexcept;
Definition: value.hpp:31

Parameters

x: values.

Return value

Returns the elementwise !(x <= 0).

The result type is logical< T >.


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

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

Parameters

cond : conditional expression

Return value

A Callable object so that the expression is_nlez[cond](x) is equivalent to if_else(cond,is_nlez(x),false(as(is_nlez(x))))
