Not sure exactly what you mean. It is well known that you should keep additional digits throughout the calculation and then drop non-significant ones for final results.

The number of digits out is only a simple function of the digits in if you're doing fairly trivial calculations.

Checkout https://en.wikipedia.org/wiki/Interval_arithmetic for what it takes to monitor precision through complex calculations (in particular, see the bits about using the taylor expansions of non-trivial functions).
