      		(since C99)

      Determines if the floating-point numberx is greater than the floating-point number (y), without setting floating-point exceptions.

      Contents

      [edit]Parameters

      x - floating-point value
      y - floating-point value

      [edit]Return value

      Nonzero integral value ifx> y,​0​ otherwise.

      [edit]Notes

      The built-inoperator> for floating-point numbers may setFE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version ofoperator>.

      [edit]Example

      Run this code
      #include <math.h>#include <stdio.h> int main(void){printf("isgreater(2.0,1.0)      = %d\n", isgreater(2.0,1.0));printf("isgreater(1.0,2.0)      = %d\n", isgreater(1.0,2.0));printf("isgreater(INFINITY,1.0) = %d\n", isgreater(INFINITY,1.0));printf("isgreater(1.0,NAN)      = %d\n", isgreater(1.0, NAN)); return0;}

      Possible output:

      isgreater(2.0,1.0)      = 1isgreater(1.0,2.0)      = 0isgreater(INFINITY,1.0) = 1isgreater(1.0,NAN)      = 0
