1-3) Determines if the floating point number
x is less than or equal to 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.Parameters
| x | - | floating point value |
| y | - | floating point value |
Return value
true if x <= y, false otherwise.
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<=.
