Hi,

I've got a text field where you put a float value into, and then it is passed it to a float variable. I then put that float variable (using setFloatValue to a NSTextField (a label). It ALWAYS comes out as some very long decimal number

Is there any way I can use what was entered exactly instead.

It needs to be a float value as it is also being passed to an OpenGL script.

Thanks

It sounds like you're running into the imprecision of floats. Not every number can be precisely represented by the floating point specification, so you might get the closest approximation that can be represented. This is why testing for equality between floats is a bad idea.

If the number is not even close, something else is going on and you'll need to be more specific, I think.

The number is close (sort of), but is there any way I can round it, at all? Like some maths or something, or a function built into Cocoa?

Thanks

I think what you want is an NSNumberFormatter.
