Multi-turn tool-use scenario.
Tools involved: VehicleControlAPI
MathAPI

User requests (one per turn):
user: I've been thinking of visiting my friend for a while now, but I'm not sure how far it is from here in Crescent Hollow. Can you help me figure this out so I can plan my trip accordingly?
user: My friend lives in Autumnville.
user: Oh, and by the way, there's something else I need help with. I want to calculate the logarithm of the distance you've just told me about, considering a base 10 with a precision of 5 digits. Could you provide me with this value as well?

Expected function call sequence:
VehicleControlAPI.get_zipcode_based_on_city
VehicleControlAPI.estimate_distance
MathAPI.logarithm
