Formula
const v1 = inputs.value1 || 0; const w1 = inputs.weight1 || 0; const v2 = inputs.value2 || 0; const w2 = inputs.weight2 || 0; const v3 = inputs.value3 || 0; const w3 = inputs.weight3 || 0; const totalWeight = w1 + w2 + w3; const weightedSum = (v1 * w1) + (v2 * w2) + (v3 * w3); const weightedAvg = totalWeight > 0 ? weightedSum / totalWeight : 0; return { weightedAverage: Math.round(weightedAvg * 100) / 100, totalWeight: totalWeight, weightedSum: Math.round(weightedSum * 100) / 100 };Value 1
