In the world of programming, occasionally we deal with large numbers that are typically not computed in JavaScript. Fortunately, the JavaScript class BigInt provides the ability to work with such numbers. BigInt allows developers to work with precise numbers in large scales without losing mathematical accuracy.
Let's take a look at how we can use the method toString, which is associated with BigInt, to convert these numbers to strings. This method allows you to convert numbers into string format, which has numerous applications. The toString method can provide output in various formats, allowing control over the data representation according to user needs.
Moreover, you can control the output format by choosing different bases (like binary, hexadecimal, etc.). This method provides several examples of using this method that I will review.
One of the most important points to note about BigInt is that BigInts cannot combine with regular numbers and calculations must be performed separately. Therefore, any time numbers need to be converted to another format, such as this toString method, it is necessary to be aware of this point.
Sample Code for Converting BigInt to String
const bigIntNumber = BigInt(12345678901234567890);
console.log(bigIntNumber.toString()); // Outputs as a regular number
console.log(bigIntNumber.toString(16)); // Outputs as a hexadecimal string
console.log(bigIntNumber.toString(2)); // Outputs as a binary string
Explanations Line by Line
const bigIntNumber = BigInt(12345678901234567890); With this statement, you create a specific BigInt number.
console.log(bigIntNumber.toString()); This statement displays the BigInt value as a regular number in string format.
console.log(bigIntNumber.toString(16)); This line converts the BigInt value into a hexadecimal string format.
console.log(bigIntNumber.toString(2)); In this line, the BigInt value is converted to a binary string format.
