Test suite has been expanded

Christian Schröder on 26 Feb 2023

As always, please don't use isequal() for comparing floating-point numbers. (My initial attempt would've failed the last test with a deviation on the order of 1e-15, for instance.)

Dyuman Joshi on 27 Feb 2023

Test suite has been updated to check tolerance instead of equality.

Thanks, Dyuman!
