|   bool isgreater( double x, double y );  | 
(2) | (since C++11) | 
|   bool isgreater( long double x, long double y );  |

1-3) Determines if the floating point number 
x is greater than the floating-point number y, without setting floating-point exceptions.4) A set of overloads or a function template for all combinations of arguments of arithmetic type not covered by (1-3). If any argument has integral type, it is cast to double.

[edit] Parameters
| x | - | floating point value | 
| y | - | floating point value | 
[edit] Return value
true if x > y, false otherwise
[edit] Notes
The built-in operator> for floating-point numbers may set FE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version of operator>.
