Hi,

ISGREATER(3)						   BSD Library Functions Manual 					      ISGREATER(3)

NAME
isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered -- compare two floating-point numbers LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <math.h> int isgreater(real-floating x, real-floating y); int isgreaterequal(real-floating x, real-floating y); int isless(real-floating x, real-floating y); int islessequal(real-floating x, real-floating y); int islessgreater(real-floating x, real-floating y); int isunordered(real-floating x, real-floating y); DESCRIPTION
Each of the macros isgreater(), isgreaterequal(), isless(), islessequal(), and islessgreater() take arguments x and y and return a non-zero value if and only if its nominal relation on x and y is true. These macros always return zero if either argument is not a number (NaN), but unlike the corresponding C operators, they never raise a floating point exception. The isunordered() macro takes arguments x and y and returns non-zero if and only if neither x nor y are NaNs. For any pair of floating-point values, one of the relationships (less, greater, equal, unordered) holds. SEE ALSO
fpclassify(3), math(3), signbit(3) STANDARDS
The isgreater(), isgreaterequal(), isless(), islessequal(), islessgreater(), and isunordered() macros conform to ISO/IEC 9899:1999 (``ISO C99''). HISTORY
The relational macros described above first appeared in NetBSD 5.0. BSD
