Block Attribute Formula and Format

[nsgma]

I have a formula that is not calculating as expected. It is probably a very basic question.

I have attribute in the block that is the height of a given element in the local relation and I want to calculate the absolute height.
After a few more complex attempts, I settled fot this:
%<UserText("block","Local_height","Height in relation to local +0.00","0")>%m (+%<int(UserText("block","Local_height"))+748>%m)
with 748 being the absolute height of the local z=0.
It seems to work only for integer number in the Local_height attribute, when I add a decimal the sum returns ####.
I’m missing something basic?
I have other similar calcs that allow the decimal (actually in some of them i’d like to remove them…)

Any one could help with this?

Here is the solution:

Replace the int with float. Int doesn’t allow fractional parts, float does.

Yes you can. This is what your %<748+float(UserText(“block”,“Local_height”))>% would need to look like to format to two decimal places:

%<'{:#.2f}'.format(748+float(UserText(“block”,“Local_height”)))>%

For a different number of decimals just change the 2 to whatever you want.

What we are doing here is using Python formatting commands to display a string with a placeholder - the curly brackets - in it which will be filled with the result of the calculation in the brackets after the format instruction. You can also put boilerplate text in the string if you want, e.g.

%<'Global Ht: {:#.2f}'.format(748+float(UserText(“block”,“Local_height”)))>%,
however that is less relevant in Rhino fields because you can build the string outside the <> anyway.
