#define isless(x, y) /* implementation defined */ | (since C99) | |
Determines if the floating-point numberx is less than the floating-point numbery, without setting floating-point exceptions.
Contents |
x | - | floating-point value |
y | - | floating-point value |
Nonzero integral value ifx< y,0 otherwise.
The built-inoperator< for floating-point numbers may raiseFE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version ofoperator<.
Possible output:
isless(2.0,1.0) = 0isless(1.0,2.0) = 1isless(INFINITY,1.0) = 0isless(1.0,NAN) = 0
(C99) | checks if the first floating-point argument is greater than the second (function macro)[edit] |
