 A document with APR calculation examples published by the EC in 2015 [is available in the `doc/` folder](doc/aprc-examples-calculation_en.pdf). All of its examples have been rewritten as PhpSpec tests under `spec/`. They not only help test the code, but may also serve as illustration of how to use the library. Additionally, a number of tests written for the original C# library have also been ported and are available there.

-\* Note of caution: at least according to the EC directives, in some cases the calculated APR will depend on the actual date that it is claimed on (leap years are involved in some cases). This is currently not taken into account by the calculator, and a year of 365.25 days is assumed. This means that there is a narrow chance of the result of the calculation actually being incorrect.
