scaling a Double

Hello Ranchers!!

I have a few Double members, with setters and getters.
I recently received a request that the getters will return a double with only two digits after the decimal points(decimal digits, that is).
e.g - the number for the number 5.123 the getter will return will return 5.12.
Now, I remembered something called "scaling" , setScale , but I can't find this method in the Double object nor in the API.

I know I can always write a small util, but I always prefer something ready.

Any suggestions??

Sounds like they really want a BigDecimal.


A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
