Approach 3 Using parseInt and toString
- Parse the input strings
num1andnum2to regular numbers usingparseInt(). - Check for division by zero by verifying if
number2is equal to zero, and throw an error if it is. - Perform the division using the
/operator betweennumber1andnumber2, and store the result. - Convert the result to a string, split it at the decimal point, and keep only the integer part for the final result. Return this integer part as a string.
Syntax:
const number1 = parseInt(num1, 10);
const number2 = parseInt(num2, 10);
Example: Below is the implementation of the above approach.
function divideLargeNumbers(num1, num2) {
// Parse the input strings to numbers
const number1 = parseInt(num1, 10);
const number2 = parseInt(num2, 10);
// Check if num2 is zero (division by zero)
if (number2 === 0) {
throw new Error("Division by zero is not allowed.");
}
// Perform the division
const result = number1 / number2;
// Convert the result back to a string
return result.toString().split('.')[0];
}
// Example usage:
const num1 = "1322145464651";
const num2 = "125";
const result = divideLargeNumbers(num1, num2);
console.log(result);
Output
