                    | Defined in header  <math.h> | ||
| #define isgreaterequal(x, y) /* implementation defined */ | (since C99) | |
Determines if the floating point number x is greater than or equal to the floating-point number y, without setting floating-point exceptions.

[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
#include <stdio.h> #include <math.h> int main(void) { printf("isgreaterequal(2.0,1.0) = %d\n", isgreaterequal(2.0,1.0)); printf("isgreaterequal(1.0,2.0) = %d\n", isgreaterequal(1.0,2.0)); printf("isgreaterequal(1.0,1.0) = %d\n", isgreaterequal(1.0,1.0)); printf("isgreaterequal(INFINITY,1.0) = %d\n", isgreaterequal(INFINITY,1.0)); printf("isgreaterequal(1.0,NAN) = %d\n", isgreaterequal(1.0,NAN)); return 0; }
Possible output:
isgreaterequal(2.0,1.0) = 1 isgreaterequal(1.0,2.0) = 0 isgreaterequal(1.0,1.0) = 1 isgreaterequal(INFINITY,1.0) = 1 isgreaterequal(1.0,NAN) = 0
