isgreater(3M) Mathematical Library Functions isgreater(3M)NAMEisgreater - test if x greater than y
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#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 excep‐
tion 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.
