One more quick thought, the method for rounding I described might cause some issues for very large/small values.

- The decimal-places check I described would not work for values with an exponential string representation – I'd suggest checking base/step for index('e'), and if it is found in either then don't perform the additional truncation.

- Also, for large values of newValue, the truncation may result in the value overflowing to infinity, so I'd suggest only rounding where (newValue < 10^21).  (This limit is the matches the cut-off where ToString conversion switches to exponential, and since values above this limit never have any decimal places in their representation we have nothing to truncate here anyway).

cheers,
G.
