The toFixed() method formats a number using fixed-point notation. function financial(x) { return Number.parseFloat(x).toFixed(2); } console.log(financial(123.456)); // expected output: “123.46” console.log(financial(0.004)); // expected output: “0.00” console.log(financial(‘1.23e+5’)); // expected output: “123000.00” OUTPUT: > “123.46” > “0.00” > “123000.00”
