SYNOPSIS
       floating-type

DESCRIPTION
       The  macro determines whether the sign of its argument value (which may
       be a floating-point number, zero, infinity, or NaN) is  negative.   The
       argument must be of floating type.  For HP Integrity servers, the argu‐
       ment can be any floating type.	For  PA-RISC,  the  argument  must  be
       either or

USAGE

       and options.  Make sure your program includes Link in the math  library
       by specifying on the compiler or linker command line.

RETURN VALUE

       ment value is negative.
