reverse-decimal.js

function reverseDecimal(num) {
  var arr = num.toString().split('.');
  arr[1] = arr[1].split('').reverse().join('');
  return parseFloat(arr.join('.'));
}

var numbers = [0.24, 0.35, 0.76];

console.log(numbers.map(reverseDecimal));

// Example: [ 0.12, 0.34, 0.56 ] --> [ 0.21, 0.43, 0.65 ]
