title: keep trailing zeros for doubla value java
body: <p>I have a function that accepts only a double value, I want that double value to appear with trailing zeros, like when I pass 100.00 I want it to be displayed 100.00 not 100.0,</p>
  <p>I don't want to use anything to do with system.out.printf() since I want it as a double value to pass it the function</p>
  <p>P.S: I cant update the function since it not mine its imported from a package.
  please help</p>
