isgreater(3M) isgreater(3M)

NAME

isgreater() - ﬂoating-point quiet 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 arguments must be of ﬂoating type. For Itanium(R)-based systems, the arguments can be any ﬂoating

type. For PA-RISC, each argument must be either

double or float.

USAGE

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). The macro raises no ﬂoating-point excep-

tions.

ERRORS

No errors are deﬁned.
