Callable Signatures

namespace kyosu
{
   //  regular call
   template<kyosu::concepts::cayley_dickson_like T> constexpr complexify_t<T> rsqrt(T z) noexcept;
 
   // semantic modifyers
   template<concepts::real T> constexpr complexify_t<T> rsqrt[real_only](T z) noexcept;
}

Parameters

• z: Value to for which square root is computed.

Return value

• A real typed input z is treated as if complex(z) was entered, unless the option real_only is used in which case the parameter must be a floating_value, the real part of the result will the same as an eve::rsqrt implying a Nan result if the result is not real.
• Returns a square root of 1/z.
