Conditional vs. Conversion

Which, in theory would be faster... using a conditional or allowing the Flash engine to automatically convert the values?

Conditional

Actionscript Code:

var output:int;
var b:Boolean = true;
var i:int = 5;
output = i + ((b) ? 1 : 0);
trace(output); // 6

Conversion

Actionscript Code:

var output:int;
var b:Boolean = true;
var i:int = 5;
output = i + b;
trace(output); // 6

Obviously, allowing Flash to convert the Boolean to a int value is easier to read, but would it be faster?

I didn't even know Flash could convert Boolean into the 1 and 0 by itself, I thought it was stricter than that. But is this really something you need to worry about? What's the time difference gonna be, like 5 milliseconds?
