NAME
islessgreater( ) - floating-point quiet comparison macro (<>)
SYNOPSIS
#include <math.h>
int islessgreater(
floating-expr x, floating-expr y);
DESCRIPTION
The islessgreater()
macro determines whether its first argument is less than or greater than its
second argument, without raising the invalid exception when x and y are unordered.
The arguments must be of floating type. For Itanium(R)-based systems, the arguments can be any float-
ing type. For PA-RISC, each argument must be either
double or float.
USAGE
To use the
islessgreater()
macro, compile either with the default
-Ae option or with the -Aa and
-D_HPUX_SOURCE
options. Make sure your program includes <math.h>. Link in the math library by
specifying
-lm on the compiler or linker command line.
RETURN VALUE
The
islessgreater()
macro returns the value 1 if (x)<(y) or ((x)>(y), and returns zero
otherwise. The macro raises no floating-point exceptions.
ERRORS
No errors are defined.
