Floor without OBSE?[edit source]
While I personally think everyone should get OBSE, some people would rather not. I was trying to do the floor function without OBSE by setting and reading variables, but I can't think of a way to do it.
anybody have any ideas?

- According to this page all integer variables are rounded to the nearest integer. So 1.9 would be rounded to 2. Instead you want to round it to 1, so how about subtracting 0.5 before putting it into a short:
- short flooredInt float decimalValue set decimalValue to 1.9 set flooredInt to decimalValue - 0.5 ;; rounding 1.4 to the nearest integer gives 1 set decimalValue to 2.0 set flooredInt to decimalValue - 0.5 ;; rounding 1.5 to the nearest integer gives 2

- It strikes me as incredibly unlikely that setting a short to a float results in rounding rather than truncation. Given the very old (read: out-of-date) nature of that article, I'd test that. If it doesn't round, then just setting a short to a float value will automatically floor it.
- But regardless, using Modulo would eliminate dependence on the particular implementation there:
short flooredInt float decimalValue set decimalValue to 1.9 set flooredInt to decimalValue - ( decimalValue % 1 ) ;; 1.9 - 0.9 = 1 set decimalValue to 2.0 set flooredInt to decimalValue - ( decimalValue % 1 ) ;; 2.0 - 0 = 2
- That template is awesome, Qazaaq, by the way.
