Why would you do this? It is not more convenient. It is actually a

A stripped down version of your code works as expected here.
- (IBAction) test:(id) sender
{
//set coordinates to x,y -> 0,0 to start
float x = 0;
float y = 0;
while (YES) {
NSLog(@"x = %f, y = %f", x, y);
x = x+100;
//if coordinates are too
I've got two float values (x and y) that I'm using to change the
coordinates of a drawing action that is being looped through. I can
add a value to x and it draws the next image along, but I want to test
the value of x and if it is out of bounds I want to reset it to zero
and increase y, so

Yes, the term is "cast".
No you didn't need to cast 299 to a float. It's not wrong to do so, just
unnecessary. (And, if you care, you could
Got it working, Part of my issue seemed to be my logic.
300 is the bounds of my target image, and I have planned it so images
fit inside this, so x would end up being 300. In a stupid moment, I
set the if statement to run if x>300, which initially it wouldn't be

Why? The two are exactly equivalent.

Personally when I am writing code, I always write as x = x + 1.0 for clarity as
well.

No, I called typecasting an int type to a floating type, in order to add it to
a floating type, unnecessary and pointless.

No, he called the specific casting you were performing unnecessary and
pointless, which it is.

That is *completely* unnecessary and pointless.

I've got two float values (x and y) that I'm using to change the
coordinates of a drawing action that is being looped through. I can
add a value to x and it draws the next image along, but I want to test
