template< class T > struct multiplies; | (until C++14) | |
template< class T = void > struct multiplies; | (since C++14) |
Function object for performing multiplication. Effectively calls operator*
on two instances of type T
.

Parameters
lhs, rhs | - | values to multiply |
Return value
The result of lhs * rhs
.
Exceptions
(none).
Possible implementation
