displaying float in android without adding trailing zero

Question

I've got a series of float numbers; I want to display them as they are; but while I use String.getValueOf .0 will be added to my numbers ie 10 is shows as 10.0 what should i do to prevent this mess ?

Don't use a float if you don't want the decimal place – takendarkk Dec 23 '13 at 17:39 — takendarkk, Dec 23 '13 at 17:39

Try

if(stringVariable.endsWith(".0")) stringVariable = stringVariable.replace(".0" , "");

This way it will remove .0 only if the string ends with .0

Hope this helps.

You can change from float to int using Math.round()

using something like sprintf would do it

String.format("%.0f", value);

can u elaborate this with an example ; let say we have 5.65656565 in an array. – Shervin4030 Dec 23 '13 at 18:02
%.0f means display a float with nothing after the . You could say %.2f if you wanted to show 2 decimal places for example. – 0xFADE Dec 23 '13 at 18:06
what if I dont know that my string is 0 or 0.121212 ; applying this doesnt give me 0.00 ? – Shervin4030 Dec 23 '13 at 18:33
Dear 0xFADE ! can you help me on this ? when I apply what you said with the accepted answer of my question; everything is right but I get 10.00 ; how do i remove those 00 ? – Shervin4030 Dec 23 '13 at 18:50
0.5 in such case will be displayed as 1 – user924 Apr 07 '21 at 13:09
