True, it's an educated guess. Floor() functions (and to a certain extent entire Math libraries)are notoriously slow in all languages, because they have to return correctly in all circumstances. The int cast will work in this case, because: 1) the number of game days passed should never exceed to max value of an integer, and 2) The number of game days passed will always be a positive number. | True, it's an educated guess.

Casting float to int faster than Math.Floor
I'd be very interested to know where this came from. Was there a test that was run, or is it just an educated guess based on the performance of other languages? If there was a test, I'd be really interested in the details of how it was run and what its results were.
