Summary

The introduction to complex arithmetic in 7.3.1p3 is wrong on several counts, all due to CMPLX.

The text in question is:

Each synopsis specifies a family of functions consisting of a principal function with one or more double complex parameters and a double complex or double return value; and other functions with the same name but with f and l suffixes which are corresponding functions with float and long double parameters and return values.

The items that are wrong are:

• CMPLX is a macro (not a function).
• CMPLX takes double parameters (not double complex).
• CMPLX has F and L suffixes (not f and l).

Proposed Technical Corrigendum

In 7.3.1#3, change:

Each synopsis specifies a family of functions

to

Each synopsis other than the CMPLX macros specifies a family of functions

(add forward reference to 7.3.9.3)
