Javascript - Number value format with comma and two decimal points

If you want to format a number in JavaScript with a comma as a thousands separator and two decimal points, you can use the toLocaleString method along with toFixed. Here's an example:

const number = 1234567.89; const formattedNumber = number.toLocaleString('en-US', { minimumFractionDigits: 2, maximumFractionDigits: 2, }); console.log(formattedNumber); // Output: "1,234,567.89"

In this example:

  • toLocaleString is used to format the number.
  • The first argument is the locale ('en-US' for English in the United States).
  • The second argument is an options object where minimumFractionDigits and maximumFractionDigits are both set to 2, ensuring that the number is formatted with exactly two decimal places.

Adjust the number variable to your actual numeric value, and the toLocaleString method will format it accordingly.

Examples

  1. "JavaScript number format with commas and fixed decimals"

    • Code:
      // Example: Format number with commas and two decimal points const number = 1234567.89; const formattedNumber = number.toFixed(2).replace(/\B(?=(\d{3})+(?!\d))/g, ",");

  2. "JavaScript number format with commas using Intl.NumberFormat"

    • Code:
      // Example: Format number with commas using Intl.NumberFormat const number = 1234567.89; const formattedNumber = new Intl.NumberFormat().format(number);

  3. "JavaScript number format with commas and custom decimal points"

    • Code:
      // Example: Format number with commas and custom decimal points const number = 1234567.89; const formattedNumber = number.toLocaleString('en-US', { minimumFractionDigits: 2, maximumFractionDigits: 2 });

  4. "JavaScript number format with commas and rounding"

    • Code:
      // Example: Format number with commas, two decimal points, and rounding const number = 1234567.895; const roundedNumber = Math.round(number * 100) / 100; // Round to two decimal places const formattedNumber = roundedNumber.toLocaleString('en-US');

  5. "JavaScript number format with commas and thousands separator"

    • Code:
      // Example: Format number with commas and thousands separator const number = 1234567.89; const formattedNumber = number.toLocaleString('en-US');

  6. "JavaScript number format with commas and dynamic decimal points"

    • Code:
      // Example: Format number with commas and dynamic decimal points const number = 1234567.895; const decimalPoints = 2; const formattedNumber = number.toLocaleString('en-US', { minimumFractionDigits: decimalPoints, maximumFractionDigits: decimalPoints });

  7. "JavaScript number format with commas and without decimal points"

    • Code:
      // Example: Format number with commas and without decimal points const number = 1234567.89; const formattedNumber = number.toLocaleString('en-US', { minimumFractionDigits: 0, maximumFractionDigits: 0 });

  8. "JavaScript number format with commas and custom separator"

    • Code:
      // Example: Format number with commas and custom separator const number = 1234567.89; const formattedNumber = number.toLocaleString('en-US', { useGrouping: true, minimumFractionDigits: 2, maximumFractionDigits: 2, groupingSeparator: '-' });

  9. "JavaScript number format with commas and no rounding"

    • Code:
      // Example: Format number with commas and no rounding const number = 1234567.895; const formattedNumber = parseFloat(number).toLocaleString('en-US', { minimumFractionDigits: 2, maximumFractionDigits: 2 });

  10. "JavaScript number format with commas and currency symbol"

    • Code:
      // Example: Format number with commas and currency symbol const number = 1234567.89; const formattedNumber = new Intl.NumberFormat('en-US', { style: 'currency', currency: 'USD' }).format(number);
