Determines if its first argument is larger than or equal to its second.
Include
<math.h>
Prototype
int isgreaterequal(floating-point x, floating-point
y);
Argument
x
y
Return Value
Determines if its first argument is larger than or equal to its second, as if
by the expression (x) >= (y)
only without any invalid floating-point
exception should the arguments be unordered (i.e. should one of them be NaN).
Example
#include <math.h>
#include <stdio.h>
int main(void)
{
double x, y;
int b;
x = -5.7;
y = 2.0;
b = isgreaterequal(x, y);
printf("That %f is greater than or equal %f is %s\n", x, y, b ? "true" : "false");
}
Example Output
That -5.700000 is greater than or equal 2.000000 is false
