is there any way in java to printf something like... (see detail)?

Question

like when you have 1.2 it will print 1.2
1.0 will print just 1
1.23 will print 1.23
1.3333 will round to 2 decimals --> 1.33
basically if it has less than 2 decimal it will not add zero, but when it has more than 2 decimals it will round to two decimal

if yes, please specify
thanks

Answer 1

Use the NumberFormat class

public String setDigits(float f)
{
NumberFormat numberformat = NumberFormat.getInstance();
numberformat.setMinimumFractionDigits(2);
return numberformat.format(f);
}

Answer 2

Yes, look at the String Formatting methods, the syntax is very similar to C tokens.

Answer 3

What Railgun means is, look at the java.lang.String class. It has a static "format" method:
String.format(String format, Object input ...)

Not sure why someone gave Railgun a negative vote. He was correct, just not very informative.
