NAME
isgreaterequal( ) - floating-point quiet 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 arguments must be of floating type. For HP Integrity servers, the arguments can be any floating
type. For PA-RISC, each argument must be either
double or float.
USAGE
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). The macro raises no floating-point
exceptions.
ERRORS
No errors are defined.
