Zooper Widget Mathematical expressions can be used both inside conditionals or in the “then” / “else” statements, so all these statements are valid:

- $(3*2)$ will write 6
- $(1>0)?(3*2)$ will write 6 is 1 > 0
- $(3*2 > 4)?Yes!:No$ will write Yes if “3*2″ is greater than 4 (so yes, it will write yes!)
- $(int(#Dm#/10) = 3 || int(#Dm#/10) = 5)? It's thirty something or fifty something$ will write “It’s thirty something or fifty something” when minute is between 30 and 39 OR 50 and 59 (so #Dm# is current minute, we divide by 10 and then we take the integer part, so, for example if #Dm# is 39 -> 39/10 = 3.9 -> int(3.9) -> 3 and 3 = 3)

Below complete reference of current accepted constants, operators and functions.
