[edit] Parameters
| x | - | floating point value |
| y | - | floating point value |
[edit] Return value
Nonzero integral value if x < y, 0 otherwise
[edit] Notes
The built-in operator< for floating-point numbers may raise FE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version of operator<.
[edit] Example
Run this code
Possible output:
isless(2.0,1.0) = 0 isless(1.0,2.0) = 1 isless(INFINITY,1.0) = 0 isless(1.0,NAN) = 0
