Custom Gist to Handle Money Formats.

handleMoney.js

const handleMoney = {
  // Converts a number format (NOT FLOAT) to a human readble money value that is typically associated to a float.
  // @param value = number
  // @output result = float
  toHuman: function(value) {
    const options = {
      minimumFractionDigits: 2
    };
    const formatter = new Intl.NumberFormat('en-AU', options);
    return formatter.format(value / 100);
  },
  // Converts a float format to a computer readble value that can be used to accuratly calculate values.
  // @param value = float
  // @output result = number
  toComputer: function(value) {
    if (typeof value === 'string') {
      value = parseFloat(value.replace(/,/gi, ''));
    }
    return value * 100;
  }
};

// Example 1 - Function Calls
const { toHuman, toComputer } = handleMoney;
const purchaseAmount = 500000; // $50.00
const HUMAN_READABLE = toHuman(purchaseAmount);
const COMPUTER_READABLE = toComputer(HUMAN_READABLE);

// Example 1 - Outputs
console.log('\nOriginal Value: ', purchaseAmount);
console.log('Human Value: ', `$${HUMAN_READABLE}`);
console.log('Computer Value: ', COMPUTER_READABLE);

// Original Value:  500000
// Human Value:     $5,000.00
// Computer Value:  500000

// Example 2 - Function Calls
const cart = [1009, 2750, 350, -1000];
const TOTAL_COMPUTED_READABLE = cart.reduce((acc, item) => (acc += item), 0);
const TOTAL_HUMAN_READABLE = toHuman(TOTAL_COMPUTED_READABLE);
const BACK_TO_COMPUTED = toComputer(TOTAL_HUMAN_READABLE);

// Example 2 - Outputs
console.log('\nTotal Computed Value: ', TOTAL_COMPUTED_READABLE);
console.log('Total Human Value: ', `$${TOTAL_HUMAN_READABLE}`);
console.log('Back To Computed: ', BACK_TO_COMPUTED);

// Total Computed Value:  3109
// Total Human Value:     $31.09
// Back To Computed:      3109
