### [SOLVED, 0.73] formula returns 0 when not complete

Posted:

**20. April 2018, 15:24**Formulas return 0 when not all variables are known. This leads to "green" final coordinates (when plausible).

A

B

3

----------------------------

C

0=f(13*A+2*B)

----------------------------

when Final should be N grey / E green, given the formula

solution: formulas shoud return "NaN" or "unknown" when not all variables are set.
