Comments on: Use Math.round not (int) - I never claimed to be perfect! http://mgmblog.com/2009/01/28/use-mathround-not-int/ My eclectic journey into the blogosphere Fri, 30 Jul 2010 01:22:18 +0000 http://wordpress.org/?v=2.3.2 By: michael http://mgmblog.com/2009/01/28/use-mathround-not-int/#comment-374 michael Wed, 28 Jan 2009 18:17:25 +0000 http://mgmblog.com/2009/01/28/use-mathround-not-int/#comment-374 Thanks Jamie, fix made to post for the incorrect value of 2.26. Tasos, I'm performing the conversion so I can take a currency value that the user has entered via an EditText view widget and convert it to an integer. I'm only doing addition and subtraction and I believe that an integer is what I want to use. Am I correct?? Thanks Jamie, fix made to post for the incorrect value of 2.26.

Also, is f*g some sort of censored swear word? ;-) Anyway, this is a good reminder as something we don't always think of but can make a big difference... “2.26 * 100 = 235.99998″ really threw me for a loop…I’m assuming that first number is supposed to be 2.36?

Use long ints to perform your calculations and just print it accordingly, that is fixed point math. Do not use floating point values!
