Solved How would I do this.

How would I get 100.0 on a message.

Code:

 ChatColor.GRAY +  " - Health: " + percent + "%"

I used

Code:

  long percent = Math.round(((float) p.getHealth() / (float) p.getMaxHealth()) 

and got 100%

 

p.getHealth() and p.getMaxHealth() both return Doubles, so if you don't cast float, it should return what you desire.

 

Doesen't really make sense?

 

If im right math round removes the .0

 

Twisted_Panda Why are you casting to float?

Percentage is gotten by dividing one number by another, then multiplying by 100. Then you can just put that right in your string.

 

I guess what you mean by your question is to have decimals at all times, also to limit to one decimal.
I would recommend you to use DecimalFormat for this.

You could do it this way (long):

Code:java

double d = 115.333; //Example
 
        DecimalFormat numf = (DecimalFormat) DecimalFormat.getNumberInstance();
        numf.setMinimumFractionDigits(1);
        numf.setMaximumFractionDigits(1);
        numf.setRoundingMode(RoundingMode.HALF_UP);
        numf.setGroupingUsed(false);
        DecimalFormatSymbols decfs = DecimalFormatSymbols.getInstance();
        decfs.setDecimalSeparator('.');
        numf.setDecimalFormatSymbols(decfs);
 
        System.out.println(numf.format(d));

or like this:

Code:java

double d = 115.333; //Example
 
        DecimalFormat decf = (DecimalFormat) DecimalFormat.getInstance(Locale.US);
        decf.applyPattern("#0.0"); // Info: "#,#00.0#" -> 1,234.56
 
        System.out.println(decf.format(d));

 

whitehooder, couldn't he get the percentage of a players health by doing this: (p.getHealth / p.getMaxHealth ) * 100 ?

Sure, that is how he would get the percentage. He could then store that percentage in the double d value and format it the way he wanted with DecimalFormat. This is useful when you have a number like 100/3=33.3333333333333 and don't want to output all the three's
