Here, x is the number whose logarithm in base 2 is to be calculated.

Return Value

The JavaScript Math.log2() method returns the logarithm of a number in base 2.

Example

The following example shows the usage of the JavaScript Math.log2() method:

[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]

// Calculate the logarithm of a number in base 2
var x = 4;
var log2x = Math.log2(x);

console.log(log2x);  // Output: 2
