Hello,
I have created a speedometer with GUIText. It works perfectly. But, it goes to too many digits. Like: 40.14364 MPH. I only want the 40 number, now everything in between. Any ways to prevent that? The tutorial I was using is here. 
You can use the Mathf.RoundToInt function to round the actual speed the nearest integer.
Thankyou. But, How would I use it?
