find the natural logarithm of a number in ruby

To find the natural logarithm of a number in Ruby, you can use the Math module's log method with a base of Math::E. Here's an example:

main.rb
number = 10
natural_logarithm = Math.log(number)

puts natural_logarithm
73 chars
5 lines

In this example, we're finding the natural logarithm of the number 10. The Math.log method takes the number as an argument and returns the natural logarithm of that number. The result is then printed to the console with puts.

Note that the Math::E constant represents the mathematical constant e, which is the base for natural logarithms.
