You can use the additional variables in the formula field for to facilitate writing the formula and displaying the result.

For Example, Formula Monthly payment for Loan:

let r = x[2] / 1200;
let A = x[1];
let N = x[3];

let result = ( r * A ) / ( 1 - Math.pow((1+r), -N));
y[1] = roundVal(result, 2);

if( x[1] < 100 ) {

} else if ( x[1] < 200 ) {
    y[1] = x[2] * 3;

Little bit weird to set it up initially to make it work, but once you get the hang of it, it is simply awesome. The YouTube video is a must, without it I would not be able to get it to work. Not using jQuery is the icing on the cake. Nicely done, very impressuve !
