How to print a float with 2 decimal places in Java?

Question

How to print a float with 2 decimal places in Java? Can I do it with System.out.print?

Answer 1

You can do it using printf method, like so:

System.out.printf("%.2f", val);

In short, the %.2f syntax tells Java to return your variable with 2 decimal places in decimal representation of a floating-point number from the start of the format specifier.

There are other conversion characters you can use besides f:

d : decimal integer

o: octal integer

e: floating-point in scientific notation
