Opencart currency conversion

Question

I have an installation of Opencart which includes multiple currency checking options. If someone changes the currency all product amounts are converted to the selected currency. I want to know where the conversion function is written within Opencart so that if a markup price needs to be added, it can be done here within the conversion.

Answer 1

Check system > library > currency as this is where all the functions are stored and read from regarding the currency. There is also a function called convert which deals with the basic conversion.
