Good day to forum members!

I have such a question-

what operations can I do with tags like #=dataitem.value# ?

In demos I saw expressions like 

#=dataitem.value + dataitem.value1 + ...# 

So, what else can I do with these ones?

Can I use any math function?

Can I round result?

One yet thing - can I work with #=dataitem.value# like operator in my .cs file? For example, convert it to value type? Something like decimal d=Convert.ToDouble("#=dataitem.value {0}", 1); ?

I'm not successful in any of these things;

Sorly, I'm new in telerik and ASP.

One more thing:

Expression like #=dataItem.Cat1Percent + dataItem.Cat2Percent + dataItem.Cat3Percent + dataItem.Cat4Percent...# calculates double values wrong.:

2.68+7.61+4.96+2.3+1.98+2.7+1.08+0.56+0.68+0.32+0.32 = 25.189999999999997

O my god, what can I do with it?
