Formulas

[Randy Kochevar]

In CODAP, is it possible to write a multi-step logic formula? I’d like to create a formula of the form: If x<=10, fLW=6.6; if x=11, fLW=1.9; if x=12, fLW=0. Is there a way to do that with the formula editor? (I realize that I might need to do it in two separate operations, which would be okay but not ideal.)

Hi Randy,

Yes, it is possible, and with a single formula (though perhaps not as elegant as one would wish). The screen shot shows how, using attributes x and fLW. It’s basically a nested ‘if/else’. Notice that there’s no last else clause so when x is 13, fLW gets no value.

if(x<=10, 6.6,
if(x=11, 10,
if(x=12,0)))
