Editor to share with you how perl calculates the logarithm with 2 as the base. I hope you will get something after reading this article. Let's discuss it together.

In Perl language, only the e-based function log is provided, but there is no related function to calculate the base 2, so how to calculate it? In fact, it is very simple, just use the formula to convert it.

Return log ($n) / log (2)

}
