NAME
isunordered - test if arguments are unordered SYNOPSIS
#include <math.h> int isunordered(real-floating x, real-floating y); DESCRIPTION
The isunordered() macro determines whether its arguments are unordered. RETURN VALUES
Upon successful completion, the isunordered() macro returns 1 if its arguments are unordered and 0 otherwise. 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 shall be an expression of real-floating type. ATTRIBUTES

NAME
islessequal - test if x is less than or equal to y SYNOPSIS
#include <math.h> int islessequal(real-floating x, real-floating y); DESCRIPTION
The islessequal() macro determines whether its first argument is less than or equal to its second argument. The value of islessequal(x, y) is equal to (x) <= (y); however, unlike (x) <= (y), islessequal(x, y) does not raise the invalid floating-point exception when x and y are unordered. RETURN VALUES
Upon successful completion, the islessequal() macro returns the value of (x) <= (y). If x or y is NaN, 0 is returned. ERRORS
No errors are defined. USAGE
