Day 2: Operators
Day 2: Operators
+ 0 comments This is the cleanest code I could come up with:
double tip = (double) tip_percent/100 * meal_cost; double tax = (double) tax_percent/100 * meal_cost; long total_cost = Math.round(meal_cost + tip + tax); System.out.println(total_cost);
The main complication here is getting rid of the integer division that will return zero for tip_percent/100. tip_percent is an integer. You can force a real division by having any element of the expression be a double, such as writing tip_percent/100.00 or by explicitly casting to double, which I think is more straightforward. Math.round takes a double and returns a long, so total_cost is a long. You could cast it to an int, but there is no need.
It can be all written in single expression, though not as readable:
System.out.println(Math.round(meal_cost * (1 + (double) tip_percent / 100 + (double) tax_percent / 100)));

+ 0 comments In js this is the solution
function solve(meal_cost, tip_percent, tax_percent){ var tipValue = meal_cost / 100 * tip_percent; var taxValue = tax_percent / 100 * meal_cost; var totalCost = meal_cost + tipValue + taxValue; console.log(Math.round(totalCost)) }
