std::log10(std::valarray)
From cppreference.com
Defined in header <valarray> | ||
template<class T > valarray<T> log10(const valarray<T>& va ); | ||
For each element in va
computes common (base 10) logarithm of the value of the element.

[edit]Parameters
va | - | value array to apply the operation to |
[edit]Return value
Value array common logarithms of the values in va
.
[edit]Notes
Unqualified function (log10) is used to perform the computation. If such function is not available, std::log10 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:
- All 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.
- All functions accepting an argument of type conststd::valarray& except begin() and end()(since C++14) should also accept the replacement type.
- All functions accepting two arguments of type conststd::valarray& should accept every combination of conststd::valarray& and the replacement type.
- The return type does not add more than two levels of template nesting over the most deeply-nested argument type.
[edit]Possible implementation
template<class T > valarray<T> log10(const valarray<T>& va ){ valarray<T> other = va;for(T &i : other){ i = log10(i);}} |
