With some inputs CBA_fnc_formatNumber will not behave as expected.

Joys of floating points

(65.2 * 10^2) % 10 = 9.99951
(65.2 * 100) % 10 = 9.99951
(65.2 * 10 * 10) % 1 = 0

Probably best to avoid floating points whenever you can.

Question is: can we improve CBA_fnc_formatNumber to be as precise as possible with all SQF tricks or is it already as good as it gets?
