The ` isgreater()` macro determines whether its first argument is greater than its second argument. The value of

Upon successful completion, the ` isgreater()` macro returns the value of (

If x or y is NaN, 0 is returned.

No errors are defined.

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.
