Hi there,
I have a whole number counting up and I would like to put a decimal in it to make it look like a US Dollar amount counting up. so the number 59 would be .59 and the number 259 would be 2.59.

I tried using the decimal method like this (00.##) but that just adds to 0's on the end of the number like this, 59 would be 59.00.

Any help would be awesome!

Thank you

I tried this
float pump1time = Math.abs(timerTextP1 / 100);
timerTextP1Pump1.setText(pump1time + "");

and it looks like its trying to work but it shows 0.0 till the count up equals 1 then it shows 1.0.
it won't show the decimal as it counts up. Weird.

do you only want to have the two digits to be followed after the precision
like if it is 25678 then it should be 256.78 or 25.678

only 2 digits after decimal like a US dollar amount.
25678 would be 256.78
thank you

I tried your way, but it changes nothing.

private int timerTextP1;
private int dollars = timerTextP1 / 100;
private int cents = timerTextP1 % 100;

System.out.format("timerTextP1 = %d.%d", dollars, cents);
timerTextP1Pump1.setText(timerTextP1 + "");

am I doing that right? it just displays the number normal

Well you need to use some other format command to set the converted string into the timerTextP1 field. It's no good using System.out.format as that just writes to the console. I am not sure what the actual method would be in Android code.

Solution 1

I'd just divide by 100 before displaying it.

Solution 2

You could try something like:

Java

int amount;
int dollars = amount / 100;
int cents = amount % 100;
System.out.format("Amount = %d.%d", dollars, cents);
