DESCRIPTION

     The following functions operate on complex floating-point values, as
     arguments and return values.  Some use single-precision complex values,
     some use double-precision complex values, and some use long double-preci-
     sion complex values, as indicated. The functions conform to the ISO/IEC
     9899:1999(E) standard. The function prototypes can be found in the header
     file complex.h.

     These are the functions that use single-precision complex values:
