isgreater(3M) isgreater(3M)
NAME
isgreater() - floating-point comparison macro (>)
SYNOPSIS
#include <math.h>
int isgreater(
floating-expr x, floating-expr
y);
DESCRIPTION
The isgreater() macro determines whether its first argument is greater than its second argument.
The value of isgreater( x,y)
is always equal to (x)>(y); however, unlike (x
)>(y),
isgreater(
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
isgreater() macro for inclusion in the C9X draft stan-
dard.
To use the
isgreater() 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 isgreater() macro returns the value of (x)>(y).
ERRORS
No errors are defined.
