How do i tranform tabel values  values rounded to steps of 0,5? ex. Value 2.66 to 2.5 and 8,76 to 9.0 in arcgis 10?

I need them to be rounded in step by 0,5.

Thers probably some easy solution, the only thing i found is round to nth. But not quite what I'm locking for..

Always greatfull for all the help we get here!

I think you can get to it through the field calculator, Python parser, using an expression like:

round<SPAN class="punctuation token">(</SPAN>!your_field_name!<SPAN class="operator token">*</SPAN><SPAN class="number token">2</SPAN><SPAN class="punctuation token">,</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="operator token">/</SPAN><SPAN class="number token">2.0</SPAN>‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

So, your examples:

2.66 * 2 = 5.32

round(5.32,0) = 5

5 / 2.0 = 2.5

8.76 * 2 = 17.52

round(17.52,0) = 18

18 / 2.0 = 9.0
