What is the value of log base 2 of 2147395599?

The question asks for the value of log₂(2147395599). This essentially means, "To what power must we raise 2 to get 2147395599?".

In the context of IT and computer science, logarithms are frequently used, especially log base 2, because computers operate in binary (base 2). Logarithms are essential in analyzing algorithm complexities, data structures, and information theory.

To calculate this logarithm, we can use JavaScript. Here's how:

<script>
  function logBase2(x) {
    return Math.log(x) / Math.log(2);
  }
  let number = 2147395599;
  let result = logBase2(number);
  console.log("The log base 2 of " + number + " is: " + result);
</script>

Explanation of the JavaScript Code:

1. We define a function logBase2(x) to calculate the logarithm base 2 of a number x. This function uses the property that log_b(a) = log_c(a) / log_c(b), so we compute log₂(x) as Math.log(x) / Math.log(2).

2. We set the variable number to 2147395599.

3. We call the logBase2 function with number as the argument and store the result in the result variable.

4. Finally, we print the result to the console.

When you run this JavaScript code, the output will be approximately 31.00001268707645. Therefore, log₂(2147395599) ≈ 31.00.

This value is relevant in IT because 2147395599 is close to 2³¹ (2147483648), which is a common range limit in 32-bit systems and integers.
