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 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 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.

STANDARDS CONFORMANCE

islessgreater(): ISO/IEC C99
