Confiforms: Rounding calculated values during registration

[its moi]

I have a form, with a field that is calculated during registration / entry. This is done with Rules for field definition >> set expression 

Total=([entry.qty]*[entry.value]/100)

And I need the result to be rounded to 2 decimals. But I do not get this to work. I am wondering where I have to set the rounding, and how. As far as I understood, the rounding can be used in form field macros. If I apply this to the form field macro in registration control, this does not work ... help appreciated :)

Have a look at the math operations supported by ConfiForms in expressions - https://wiki.vertuna.com/display/CONFIFORMS/Supported+math+operators%2C+formulas+and+functions

hint: ROUND is also supported

I have seen that @Alex Medved _ConfiForms_ but still cannot get it to work. I tried to apply this to the form field macro in registrations control, in which the expression is set by rules for field definition. 

ROUND(fieldname,2) 

Or do I need to add this to the formula in Rules for field Definition which does the calculation and sets the expression?

Not sure what is this what you have...

ROUND(fieldname,2) 

but the formula to ROUND will be something like

Total=(ROUND([entry.qty]*[entry.value]/100, 2))

or

Total=(SCALE([entry.qty]*[entry.value]/100, 2))

depends what you need exactly with the value you have calculated

Thanks @Alex Medved _ConfiForms_ - the last one for the Formula did it. (y)

I tried that before but had it like which did not do the trick 

Total=(ROUND([entry.qty]*[entry.value]/100), 2)

Sorry, not really sure I understand your comment... Could you please rephrase it? Something still does not work for you?
