# How to limit calculations to one decimal place?

 0 What I want to do is have a timer on top of the screen counting how long you have been alive. The code for it is simple, and it works: ``````var aliveTime : float = 0; function Update () { aliveTime += Time.smoothDeltaTime; guiText.text = "Time: " + aliveTime; } `````` The problem is, it shows 7 places after the decimal. I want it to show just one so it looks like this: 70.7. I do not want it the other way as it is VERY distracting and no need for it to be so precise. I would like to know how to do this as it will help keep track of scores and what not. more ▼ asked May 16 '10 at 11:13 PM xToxicInferno 485 ● 24 ● 28 ● 41 SisterKy 2.4k ● 33 ● 41 ● 59 add new comment (comments are locked) 10|3000 characters needed characters left ▼ Viewable by all users

 0 Use this: ``````guiText.text = "Time: " + aliveTime.ToString("f1"); `````` more ▼ answered May 16 '10 at 11:48 PM Eric5h5 80.3k ● 42 ● 132 ● 521 Works perfectly! Thank you for that one...and as usual with one problem solved, a dozen more come up! May 16 '10 at 11:55 PM xToxicInferno I've been looking for that too for a couple of hours! - thanks a bunch Eric5h5! Dec 07 '10 at 06:54 PM schwertfisch sorry to ask a question here, but does f2 mean 2 decimal places, and f3 mean 3 decimal places and so on? Dec 23 '10 at 05:46 PM Jesus_Freak Give it a try and see. Dec 23 '10 at 07:06 PM Eric5h5 I really needed this too! Thanks so much.

 0 I think this question was asked a while ago (though QATO doesn't seem to give the year with the date), but in case anyone comes across it:To round floats to arbitrarily decimal places without converting to strings (as in Eric5h5's solution), you can use (as a general solution): ``````function round(x, decimalPlaces) { return Mathf.Round(x * Mathf.Pow(10, decimalPlaces)); } ``````If you specifically only ever want one decimal place: ``````rounded = Mathf.Round(unrounded*10)/10; ``````Or two: ``````rounded = Mathf.Round(unrounded*100)/100; ``````And so on...(As an aside, you can also use this kind of technique to round to the nearest anything: e.g. to round to nearest interval of 0.3 by using `Mathf.Round(x/0.3)*0.3`.) more ▼ answered May 01 '12 at 06:55 PM Comaleaf 83 ● 3 ● 7 ● 7 I found this to be equally as useful as Eric's suggestion, thank you!, Lauren.
