Discussion: The Mathemagician
Execute the code to understand the output and gain insights into the limitations of representing very large numbers accurately in JavaScript.
Verifying the output
Now, it's time to execute the code and observe the output.
const largeNumber = Math.pow(10, 16);const smallNumber = 1;console.log(largeNumber + smallNumber);
Understanding the output
In JavaScript, the Math.pow() function can be used to raise a number to a specified power. In this case, the code Math.pow(10, 16) calculates the result of raising the number 10 to the power of 16, resulting in 10000000000000000. But why does the sum of 10000000000000000 and 1 equal 10000000000000000?
JavaScript number’s precision
JavaScript does have some limitations when it comes to representing very large numbers accurately. The limitation is due to the way numbers are stored and the precision of the data type used in JavaScript. The Number type has a specific range where it works best. It can handle integers between -9007199254740991 and 9007199254740991 perfectly without losing any precision.
But if we happen to use an integer outside of this range, there’s a chance that it won’t be represented accurately. This issue is known as loss of precision when dealing with large numbers in JavaScript. ...
