Guardian Native C Library Calls (g - i) isgreater(3)
NAME
isgreater -Testsifx is greater than y
LIBRARY
H-series and J-series native Guardian processes: $SYSTEM.ZDLLnnn.ZCREDLL
32-bit H-series and J-series OSS processes: /G/system/zdllnnn/zcredll
64-bit H-series and J-series OSS processes: /G/system/zdllnnn/ycredll
SYNOPSIS
#include <math.h>
int isgreater(
floating-type x,
floating-type y);
PARAMETERS
floating-type Specifies the floating-type of x.
x Specifies a value of type floating-type.
floating-type Specifies the floating-type of y.
y Specifies a value of type floating-type.
DESCRIPTION
The isgreater() macro determines whether its first argument is greater than its second argument.
The value of the isgreater() macro is always equal to (x)>(y); however, unlike (x)>(y), the
isgreater() macro does not raise the invalid exception when x and y are unordered.
The arguments must be of floating type.
NOTES
This macro is implemented only for the IEEE_float floating-point option. Applications using
this macro cannot be compiled if the specified floating-point option is Tandem_float.
RETURN VALUES
Upon successful completion, the isgreater() macro returns the value of (x)>(y). If x or y is
NaN, 0 (zero) is returned.
ERRORS
No errors are defined.
