[TYPO3] Math in TypoScript

[Bertalan Fodor]

Note I'm trying to define constants calculated from each other.

Do you know that there is information about what I need in TSRef, or do 
you only hope so? I have searched in TSRef for the word "calcul", and 
have read everything. So did I try setting x2 = 13 + 5, but didn't work.

Because these are constants: should I set the type, because otherwise it 
is interpreted as text?  I tried that either. (in the comment, using 
type) Note there is nothing about constant types in TSRef.

Thanks,

Bert
