While the Ceiling function by definition returns the smallest integer >= x, I found myself wishing it could accept a precision argument the way Round does. The FlexCeiling custom function allows this to happen.

Essentially, FlexCeiling is a "magic Round" that always makes a number larger -- regardless of whether that number is positive or negative -- whereas Rounding (via the Round function) a negative number "up" actually makes it smaller (more negative).

E.g., Round ( -4.7 ; 0 ) = -5 whereas FlexCeiling ( -4.7 ; 0 ) = -4

Note: see also the companion custom function, FlexFloor.
