Checking the last digit of an integer value in JavaScript/p5

In JavaScript/p5.js, you can check the last digit of an integer value using the modulo operator (%). The modulo operator returns the remainder of a division operation. To get the last digit of an integer, you can calculate the remainder of the integer divided by 10.

Here's how you can check the last digit of an integer in JavaScript/p5.js:

javascriptCopy code
// Function to check the last digit of an integer
function checkLastDigit(number) {
  // Calculate the last digit using the modulo operator
  const lastDigit = number % 10;

  // Return the last digit
  return lastDigit;
}

// Example usage
const num = 12345;
const lastDigit = checkLastDigit(num);
console.log("Last Digit:", lastDigit); // Output: Last Digit: 5

In the example above, the checkLastDigit function takes an integer as input, calculates the last digit using the modulo operator %, and returns the last digit. When you call the function with num = 12345, it will output 5, which is the last digit of the number.
