find the base 2 logarithm of a number in ruby

To find the base 2 logarithm of a number in Ruby, you can use the Math.log2() method. This method takes a number as an argument and returns the base 2 logarithm of that number.

Here's an example:

main.rb
number = 16
log = Math.log2(number)
puts log
45 chars
4 lines

Output:

main.rb
4.0
4 chars
2 lines

In this example, we set the variable number to 16, and then use the Math.log2() method to find the base 2 logarithm of that number. The result is 4, which is printed to the console using puts.

You can replace the 16 with any number you want to find the base 2 logarithm of.
