Describe the New Feature

I want to add logic to the calculator application so that when one number is provided, it will calculate the natural log (ln) of the value.

For example, if the following POST data is sent to the application:

data = {
    "operation": "natural_log",
    "number_1": 543, # Key and value required
    "number_2": None # Key must be supplied but its value is not used
}

The result will be:

Result: 6.29710931993394

Describe Why the New Feature Should be Added

This task is required for next release for the customer.
