NAME
isgreater - test if x greater than y SYNOPSIS
#include <math.h> int isgreater(real-floating x, real-floating y); DESCRIPTION
The isgreater() macro determines whether its first argument is greater than its second argument. The value of isgreater(x, y) is equal to (x) > (y); however, unlike (x) > (y), isgreater(x, y) does not raise the invalid floating-point exception when x and y are unordered. RETURN VALUES
Upon successful completion, the isgreater() macro returns the value of (x) > (y). If x or y is NaN, 0 is returned. ERRORS
No errors are defined. USAGE
The relational and equality operators support the usual mathematical relationships between numeric values. For any ordered pair of numeric values, exactly one of the relationships (less, greater, and equal) is true. Relational operators can raise the invalid floating-point exception when argument values are NaNs. For a NaN and a numeric value, or for two NaNs, just the unordered relationship is true. This macro is a quiet (non-floating-point exception raising) version of a relational operator. It facilitates writing efficient code that accounts for quiet NaNs without suffering the invalid floating-point exception. In the SYNOPSIS section, real-floating indicates that the argument is an expression of real-floating type. ATTRIBUTES
