Hi everyone, it's been a while since I have messed around with JavaScript so this might be simple for someone who is able to help 🙂. I'm currently working on a calculator which seems to work fine for the first bit of the code regarding the compound elements, however with the variables under blend var bPrice = parseFloat(objectInputs["blend-price"]); the calculation I have for these elements are doubling but should be half of the compound elements , I have included the current script below as this was created from another developer so any help would be much appreciated 🙂
JavaScript:
"use strict";
function roundToFixed(value, precision) {
var multiplier = Math.pow(10, precision || 0);
return (Math.round(value * multiplier) / multiplier).toFixed(precision);
}
var calculatorCompoundvsblended = {
nameCalculator: "compoundvsblended",
result: function result(objectInputs) {
// Inputs
var cPrice = parseFloat(objectInputs["compound-price"]);
var cnContent = parseFloat(objectInputs["compound-n-content"]);
var cpContent = parseFloat(objectInputs["compound-p-content"]);
var ckContent = parseFloat(objectInputs["compound-k-content"]);
var csContent = parseFloat(objectInputs["compound-s-content"]);
var bPrice = parseFloat(objectInputs["blend-price"]);
var bnContent = parseFloat(objectInputs["blend-n-content"]);
var bpContent = parseFloat(objectInputs["blend-p-content"]);
var bkContent = parseFloat(objectInputs["blend-k-content"]);
var bsContent = parseFloat(objectInputs["blend-s-content"]);
var cropYield = parseFloat(objectInputs["crop-yield-cvsb"]);
var cropPrice = parseFloat(objectInputs["crop-price-cvsb"]);
var cropNRate = parseFloat(objectInputs["crop-n-rate-cvsb"]);
var cropLoss = parseFloat(objectInputs["blend-loss"]);
// Calculations
// Outputs
