const formatTwoDecimals = (num, decimals) => num.toLocaleString('en-US', {
  minimumFractionDigits: 2,
  maximumFractionDigits: 2,
});

let num1 = 3.7;
let num2 = 12.8941;
let num3 = 3.005;
let num4 = 8.245;

console.log(formatTwoDecimals(num1));
console.log(formatTwoDecimals(num2));
console.log(formatTwoDecimals(num3));
console.log(formatTwoDecimals(num4));

  
    
    
/*
run:

"3.70"
"12.89"
"3.01"
"8.25"
    
*/
