How to useMath.floor() Method in Javascript
This method involves a combination of floor division and multiplication to isolate the last digit of each number. The steps are as follows:
- Divide each number by 10 and take the integer part (floor division) to remove the last digit.
- Multiply the result of the division by 10 to get a number ending in zero.
- Subtract this number from the original number to isolate the last digit.
- Compare the isolated last digits using the strict equality operator (===).
- Return true if the last digits are the same, otherwise return false.
Example:
// Define function to check if two numbers have the same last digit
function haveSameLastDigit(num1, num2) {
// Isolate the last digit using floor division and multiplication
const lastDigit1 = num1 - Math.floor(num1 / 10) * 10;
const lastDigit2 = num2 - Math.floor(num2 / 10) * 10;
// Return if last digits are same or not
return lastDigit1 === lastDigit2;
}
// Define two numbers
const number1 = 123;
const number2 = 453;
// Calling function with arguments
const result = haveSameLastDigit(number1, number2);
// Output the result
console.log(result);
Output
true
