Raises a value to a power.
base raised to the power specified by the corresponding element from the numeric array exp.The behavior is undefined if base.size() != exp.size().
base raised to the power vexp.vbase raised to the power defined by the elements in the numeric array exp.| base | - | numeric array containing the values of the base |
| exp | - | numeric array containing the values of the exponent |
| vbase | - | a value defining the base |
| vexp | - | a value defining the exponent |
A numeric array containing the results of exponentiation.
Unqualified function (pow) is used to perform the computation. If such function is not available, std::pow is used due to argument dependent lookup.
The function can be implemented with the return type different from std::valarray. In this case, the replacement type has the following properties:
const member functions of std::valarray are provided. std::valarray, std::slice_array, std::gslice_array, std::mask_array and std::indirect_array can be constructed from the replacement type. const std::valarray& except begin() and end() (since C++14) should also accept the replacement type. const std::valarray& should accept every combination of const std::valarray& and the replacement type. applies the function std::sqrt to each element of valarray (function template) |
