NAME
isgreaterequal( ) - floating-point comparison macro (>=)
SYNOPSIS
#include <math.h>
int isgreaterequal(
floating-expr x, floating-expr y);
DESCRIPTION
The isgreaterequal()
macro determines whether its first argument is greater than or equal to its
second argument. The value of
isgreaterequal(
x,y)
is always equal to (x)>=(y); however,
unlike
(x)>=(y), isgreaterequal(
x,y) does not raise the invalid exception when x and y are
unordered.
The macro can be used with either
double
or float arguments.
The ISO/ANSI C committee has approved the
isgreaterequal()
macro for inclusion in the C9X draft
standard.
To use the
isgreaterequal()
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 isgreaterequal()
macro returns the value of (x)>=(y).
ERRORS
No errors are defined.
