I am a beginner in JavaScript. I wrote this function to calculate the percentage of three values, but the output is showing incorrectly. It is showing 176.33 instead of 74.3
function percentageCalculator(history, math, science) {
let percentage = history + math + science * 100 / 300;
console.log(percentage);
};
percentageCalculator(88, 65, 70);It should be:
let percentage = (history + math + science) * 100 / 300;
Like math, JavaScript also have calculation order.
After adding the appropriate surrounding brackets. You could just divide by 3 directly instead of multiplying by 100 and then dividing by 300:
function percentageCalculator(history, math, science) {
const percentage = (history + math + science) / 3;
return percentage;
}
console.log(percentageCalculator(88, 65, 70).toFixed(1));
