◆ exp10

eve::exp10 = {}
inlineconstexpr

Callable object computing \(10^x\).

Required header: #include <eve/function/exp10.hpp>

Members Functions

Member Effect
operator() the computation of exp10
operator[] Construct a conditional version of current function object

template< real_value T> auto operator()( T x ) const noexcept;

Parameters

x: floating real value.

Return value

Returns the elementwise exponential of base 10 of the input. In particular, for floating inputs:

  • If the element is \(\pm0\), \(1\) is returned
  • If the element is \(-\infty\), \(+0\) is returned
  • If the element is \(\infty\), \(\infty\) is returned
  • If the element is a NaN, NaN is returned

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

Higher-order function generating a masked version of eve::exp10

Parameters

cond : conditional expression

Return value

A Callable object so that the expression exp10[cond](x, ...) is equivalent to if_else(cond,exp10(x, ...),x)
