__GNU_PARALLEL::_MULTIPLIES(3)
π __gnu_parallel::_Multiplies< _Tp1, _Tp2, _Result > π
okay bestie, welcome to the libstdc++ Library Functions Manual, section 3 π this one's a lil template struct and she's lowkey iconic, so let's get into it β¨
β¨ NAME β¨
__gnu_parallel::_Multiplies< _Tp1, _Tp2, _Result > β it's giving std::multiplies, but the way that it lets you use two different types?? yeah. not me being obsessed. π
πΈ SYNOPSIS πΈ
#include <base.h>
She inherits from std::binary_function< _Arg1, _Arg2, _Result > π«Ά
π Public Types
typedef _Arg1 first_argument_typeβ bestie this is literally the type of the first argument, that's it, that's the whole job πtypedef _Result result_typeβ and this one? the return type. the moment of truth. the main character. β¨typedef _Arg2 second_argument_typeβ second verse same as the first, it's the type of the second argument πΈ
π¦ Public Member Functions
_Result operator() (const _Tp1 &__x, const _Tp2 &__y) constβ the actual call operator, she takes__xand__yand hands you back a_Resultπ
π Detailed Description π
template<typename _Tp1, typename _Tp2, typename _Result =
__typeof__(*static_cast<_Tp1*>(0) *
*static_cast<_Tp2*>(0))>
struct __gnu_parallel::_Multiplies< _Tp1, _Tp2, _Result >
"Similar to std::multiplies, but allows two different types."
no cap, that's the entire vibe. std::multiplies said "same type only sorry" and _Multiplies said "not on my watch" π§π
π Member Typedef Documentation π
these three are all inherited, meaning they come from the parent, she didn't have to do a thing, they were just handed to her β¨
template<typename _Arg1, typename _Arg2, typename _Result>
typedef _Arg1
std::binary_function< _Arg1, _Arg2, _Result >::first_argument_type
[inherited]
first_argument_type is the type of the first argument. periodt. π
template<typename _Arg1, typename _Arg2, typename _Result>
typedef _Result
std::binary_function< _Arg1, _Arg2, _Result >::result_type
[inherited]
result_type is the return type. the payoff. the finale. π
template<typename _Arg1, typename _Arg2, typename _Result>
typedef _Arg2
std::binary_function< _Arg1, _Arg2, _Result >::second_argument_type
[inherited]
second_argument_type is the type of the second argument. and that's the trio bestie, we ate π

lowkey reminder: she's a template, so_Tp1,_Tp2and_Resultall get filled in by you, and_Resultdefaults to__typeof__(*static_cast<_Tp1*>(0) * *static_cast<_Tp2*>(0))if you don't wanna pick one yourself π«Ά
and that's a wrap on libstdc++'s __gnu_parallel::_Multiplies< _Tp1, _Tp2, _Result >(3) page, mwah π go forth and multiply (two different types) bestie, ily, bye!! πβ¨ππ¦πΈπ
