isgreaterequal() — floating-point quiet comparison macro (>=)


#include <math.h>

int isgreaterequal( floating-expr x, floating-expr y);


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.


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.


The isgreaterequal() macro returns the value of (x) >= (y). The macro raises no floating-point exceptions.


No errors are defined.
