Falsehoods programmers believe about prices

You can store a price in a floating point variable.
All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
All currencies are subdivided in decimal units (like dinar/fils)
All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
For any currency you can have a price of 1. (ZWL)
Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

	1) Generate a private key and certificate signing request:

	openssl genrsa -out ios_distribution.key 2048
	openssl req -new -key ios_distribution.key -out ios_distribution.csr -subj '/[email protected], CN=Example, C=US'

	2) Upload CSR to apple at: https://developer.apple.com/account/ios/certificate/create
	- choose Production -> App Store and Ad Hoc

	3) Download the resulting ios_distribution.cer, and convert it to .pem format:

	First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py
	$ cd <download location>
	$ sudo -H python ./get-pip.py

	Installing pip also installs Python3
	To run Python3
	$ python3

	Install pip3 by just executing the same file as in the step above, but this time using Python3
	$ sudo -H python3 ./get-pip.py
