Cloedu Posted August 26, 2008 Report Share Posted August 26, 2008 Hello, i have found unexpexted rounding effects with the function "Round to nearest integer" Input 0.5 output 0 Input 1.5 output 2 Input 2.5 Output 2 Input 3.5 Output 3 Labview is alwas rounding to a even integer.... but why? What is the sense of these implementation of auf Rounding alghorithm? Thanx Claude Quote Link to comment

LAVA 1.0 Content Posted August 26, 2008 Report Share Posted August 26, 2008 This is standard behavior and noted in the help. I've just written a wiki article on rounding. Ton Quote Link to comment

I hope this helps a bit edit: Ton was a bit quicker in typing as me... Quote Link to comment

From message by Lew Drake Process Automation Corporation, and the info LabVIEW mailing list, 4/12/07. This method accumulates less error over time, it is statistically defensible. If you look around on line you will find detailed explanations, no problem. Quote Link to comment

Yair Posted August 26, 2008 Report Share Posted August 26, 2008 If you want to implement common rounding, you can do this by adding 0.5 and then rounding down. Here's an example. Quote Link to comment
