std::log10(std::valarray)

From cppreference.com
< cpp‎ | numeric‎ | valarray
 
 
 
 
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.

Contents

[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:

[edit]Possible implementation

template<class T > valarray<T> log10(const valarray<T>& va ){ valarray<T> other = va;for(T &i : other){ i = log10(i);}}
