How do you format a number to 2 decimals in java?

Question

I'm going crazy! I've searched the java sites, and ran google searches, but can't figure out how to format a normal double variable to display just the first two decimals. I can get it to work with currency, but can't figure out how to do it normally. Help me please! I'm using an IDE Eclipse to write my program.

Answer 1

import java.text.DecimalFormat;
...
DecimalFormat df = new DecimalFormat( "#########0.00");
String formattedValue = df.format(someDoubleValue);

Use ".00" if you always want to see two numbers past the decimal point. Use ".##" if you only want to see numbers if they're non-zero. For example "3.1" formated "0.00" is "3.10" but formatted "0.##" is "3.1".

Answer 3

Currently in the market, most of the monetary value would be stored in BigDecimal.

Example:
BigDecimal d = new BigDecimal(1.233);
System.out.println(" big d val > " + d);
System.out.println(" big d val in 2 decimal > " + d.setScale(2, BigDecimal.ROUND_UP));


- setScale 2 means 2 decimal points.
- BigDecimal.ROUND_UP is one of the option, u may choose to ROUND_DOWN, ROUND_FLOOR, etc

:) Since u are using eclipse, the rest should b easy for u
