Re: Round...
If you know the number of decimal places you require you can round the number yourself. i.e. if you require 2 places use: RoundedNo = 3,213,123.4590 + 0.005 you will get 3,213,123.46 (ignoring the decimals places beyond the 2nd) If you are working with money, you should stick with integers as you will loose precision (and change). Either scale a long or use two integers. - Original Message - From: "Mihai Ciornei" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Tuesday, February 17, 2004 2:39 AM Subject: Round...

Sounds like you need MathLib. See the CW project wizard -- its a shared
library that implements floating point math functions. More docs in CW for
Palm OS Support/(Other SDKs)/MathLib.
