Callable Signatures

namespace kyosu
{
   //regular call
   template<typename ... Ts> auto maxmag(Ts ... zs       ) const noexcept// 1
   template<typename Tup>    auto maxmag(kumi::tuple Tup ) const noexcept// 2
}

Parameters

• zi...: cayley_dickson_like to process.
• tup: tuple of cayley_dickson_like values to process.

Return value

1. Returns elementwise the value which has the maximum of the absolute values between the parameters.
2. Returns elementwise the value which has the maximum of the absolute values between tuple members.
