float norm1_complex_Float (CESI ptr);

Finds the 1-norm of a complex number entry.

norm1_complex_Float finds the 1-norm (i.e. the sum of absolute values of real and imaginary part) of the complex number entry pointed to by ptr and returns the result. If the entry is not a complex or real floating point number, the result is garbage (in the case of a real number, norm1_complex_Float reduces to a simple absolute value).
