How to remove decimals from Vector3.Distance

Question

How do I remove the decimals from my script so that my text mesh doesn't show something like 20.62634325 meters?

 var Other : Transform;
 
 function Start () {
 
 }
 
 function Update () {
 
   transform.localRotation = Other.localRotation;
 
 
 }

Well there's absolutely no reference to anything in that code you posted, so not sure how that's supposed to help.

There are a couple easy ways to drop the extra digits:

 displayValue:int = Mathf.RoundToInt(floatValue);

or

 displayValue:int = (int)floatValue;

ToString() can be overloaded:

 float fl = 0.1234567f;
 print(fl.ToString("0.00")); // prints 0.12

This. Ignore the other answers.

You can format also Vector3's the same way which can be very useful for debugging, especially as the default is only 1 decimal place.

 >  (Vector3.up*0.04f).ToString();
 (0.0, 0.0, 0.0)
 >  (Vector3.up*0.04f).ToString("0.00");
 (0.00, 0.04, 0.00)

Thank you Louis, but there's this thing with the distance, it's too much, like this: alt text

Please don't ignore the fact that you can convert floats to integers :P

No don't ignore that fact entirely... just ignore it when you want a float as a String for display at a certain precision :)

Multiply by 100, convert to an int, then convert back to a float and divide by 100, that will give you just 2 decimal places.
