More than one color to resistor number, what to do?

Resistor color coding (the electronic color coding) has more than one color combination to resistor value. How do you know which one to use?

I'm a lackluster soldering noob who's trying to get used to basic electronics, and thus have started to rewrite this calculator
as a learning exercise.
This ran into the issue that you can have a resistor of (brown, black, brown) which has the same value, 100 ohms, as a resistor of (black, brown, red).
What's the rule for determining a 'canonical' color code - should you maximize the exponent? Or minimize it? I'm finding it hard to find the answer from Wikipedia and such. Thanks!
