Hello,
I want to change
14201
to
14.2k
using NumberFormat
How can i do this?

[dunnkers]

I've a little start:

formatter = new DecimalFormat("#'k'");
s = formatter.format(14201); // 14201k

[dunnkers]

bump.. anyone?

You could start by looking at it as a string. The length of the string tells you how many characters you need before the new decimal.

[dunnkers]

That will result in a long if statement maze.

[WingedPanther]

Why would it do that? Are you supporting more suffixes than k? It's mostly a little math.

[dunnkers]

Can you give me an example please?

I don't think you can divide by 1000 to drop the last numbers with the formatting.
A short version would be:

NumberFormat formatter = new DecimalFormat("#0.#k");

System.out.println(formatter.format(14201.0/1000.0));

But you have to do /1000.0 yourself (.0 because it has to be doubles)

What wingedpanther wanted to do would be something like the following i guess:

int number = 12345;

double doubleNumber = number;

doubleNumber /= 100;

doubleNumber = Math.round(doubleNumber);

doubleNumber /= 10;


System.out.println(doubleNumber + "k");

I'd convert it to a string first. Then display the first n-3 characters, a decimal, and the last of the n-2 characters, and a "k".

Ah ye, probably even easier :D
