26 Numerics library [numerics]

The following function templates shall have additional overloads:

arg                   norm 
conj                  proj
imag                  real 

The additional overloads shall be sufficient to ensure:

1. 1.

   If the argument has type long double, then it is effectively cast to complex<long double>.

2. 2.

   Otherwise, if the argument has type double or an integer type, then it is effectively cast to complex<double>.

3. 3.

   Otherwise, if the argument has type float, then it is effectively cast to complex<float>.

Function template pow shall have additional overloads sufficient to ensure, for a call with at least one argument of type complex<T>:

1. 1.

   If either argument has type complex<long double> or type long double, then both arguments are effectively cast to complex<long double>.

2. 2.

   Otherwise, if either argument has type complex<double>, double, or an integer type, then both arguments are effectively cast to complex<double>.

3. 3.

   Otherwise, if either argument has type complex<float> or float, then both arguments are effectively cast to complex<float>.
