Question

Inside my function there is an if() statement like this:

if(passedValue < staticValue)

But I need to be able to pass a parameter dictating whether the if expression is like above or is:

if(passedValue > staticValue)

But I cant really pass < or > operator in has a parameter, so I was wondering what is the best way to do this?

Also if the language I am using matters its ActionScript 3.0

Thanks!!

Instead of passing an operator, which is impossible in AS3, why not pass a custom comparison function?

function actualFunction(passedValue:Number, compareFunction:Function) {
    /* ... */

    if(compareFunction(passedValue, staticValue)) {
        /* ... Do something ... */
    }

    /* ... */
}

Then to use it:

actualFunction(6, function(x:Number, y:Number) {
     return x > y;
});

or:

actualFunction(6, function(x:Number, y:Number) {
     return x < y;
});
