How does mathjs.log2 work?

mathjs.log2() is a function in the Math.js library that returns the base-2 logarithm of a number. Specifically, it returns the power to which the number 2 must be raised to obtain the input value.

const math = require("mathjs");

const result = math.log2(8); // Calculates the base 2 logarithm of 8
console.log(result); // Output: 3

In this example, mathjs.log2 is used to calculate the base 2 logarithm of the number 8, which should equal 3. The result is then logged to the console.
