[Simple Question] g.drawImage() - with "double" arguments for location

Question

I think the subject says it all, I'm looking for something kind of like this:
double x = 7.5;
double y = 2.4;
g.drawImage(img, x, y, this);Thanks,
Nate

I'm just trying to slow down a picture thats moving around the screen, but the design is kinda complex. I guess I just need to think about it.There's a technique in programming about making something time-based as opposed to frame based. Usually we start off making something frame base and end up getting fustrated when drops or speed ups in the fps cause drastic effects in the smoothness of the game/animation.
To combat this we make a program time based by storing a global variable, say "frameSpeed". We then program as though it were a constant 30 fps (or any other arbitrary number). The "frameSpeed" would then be +30 / actual fps+ . So if we were moving at 60 fps then "frameSpeed" would be .5.
This global variable is then used in all the calculations. So where as previously we may have had
x += xSpeedwe now have
x += xSpeed * frameSpeedWhen you introduce more complex concepts like acceleration the math is a little harder. But if you can make your program time based, then it will be smooth across many frame rates. You could even forcefully manipulate "frameSpeed" to cause your whole program to speed up or slow down into a bullet-time effect.
