Decimal issue's

So I try to devide 2 integers, that would result in a double. But the issue is, it keeps rounding it to 0 decimals.
So for instance if the kills are 50 and the deaths are 20, it says that k/d is 2.0 while that is not the case.

This is my code:

Code:java

 double kd = plugin.getConfig().getInt(
"kills." + player.getName())
/ plugin.getConfig().getInt(
"deaths." + player.getName());
player.sendMessage(ChatColor.GREEN + "Your K/D: "
+ ChatColor.RED + kd);
 

How do I make it so that it rounds the double to 2 decimals? Example: K/D = 2.56

Thank you!

 

Code:java

Math.round(number * 100.0) / 100.0;

 

That doesn't seem to work, I tried it.
Also the main issue is, that it doesn't show a double. it shows an integer with one decimal 0
For example: 1.0

Anyone know what's wrong?

When you divide two integers in java it will return the outcome as int form. Try casting them to a double when you do the calculation.

Try this

Code:java

 
int kills = plugin.getConfig().getInt(
"kills." + player.getName());
int deaths = plugin.getConfig().getInt(
"deaths." + player.getName());
double kd = (double) kills / (double) deaths;
player.sendMessage(ChatColor.GREEN + "Your K/D: "
+ ChatColor.RED + kd);
 

Edit: Or if I'm not mistaken you can even use the getDouble() method to ensure the number you are getting is already a double.

Perfect! It works, but the only issue now is, how do I make it so that it rounds it to 2 decimals? I tried Derpiee 's method but it gives errors: The left-hand side of an assignment must be a variable.
Thanks!

Derpiee Method should work fine for rounding to 2 decimals.

Can you post what you are trying?

 

Yes ok, it works, sorry forgot to look!
Thank you!
