yes, but boolean formulas has not the wanted effect...
1) (operation) * (condition > 0).... not good
2) $condition > 0 ? aaaaa : bbbbb $ not good
3) (operation) * sign(parameter) that's what I said <<<<<<
for example, if a VAR is negative a formula must become negative and vice versa
(I was buolding a scroll effect connected to INC or DEC of a variable and it must go up or down)
in this watchface I found a workaround: https://www.facer.io/watchface/mBeEWIr23R
$(#DNOW#-#VAR_3_T#)<500?(167+#VAR_5#*(#DNOW#-#VAR_3_T#)/25):167$ is the Y coordinates of the number (day, month or year) when setting birthdate; here VAR_5 is a flag that give the sign to the result but I have to put a INCVAR, a DECVAR and behind a RESET VAR so every time I tap it the variable turn to 0 and then goes to -1 or +1 to have the wanted sign
