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

isgreater, isgreaterequal, isless, islessequal, islessgreater, isunorderedcompare 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() takes arguments x and y and returns 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, returning non-zero if either x or y is NaN. 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'').BSD
