< 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.


[edit] Parameters

va - value array to apply the operation to

[edit] Return value

Value array containing 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);
    return other;
