In general no.  In the special case of mod 550, maybe.

Consider this.  Reach back to when you were 14 and learned floating 
point.  Suppose variable adjustment is a power of 2.  Then only the 
exponent component of the floating point value will change.  All 
arithmetic will be the same except for an offset in the exponent.

Add 1 to a large number and you will see you still have the problem.

I think it would be nice if it would distance you until until you 
really need the low level (as in file, TCP or serial I/O in some 
cases); then it should give you the low-level tools.
