Calculate significant digit calculations may be exponentializing Integer numbers one digit early

[greenfeld]

1. Set Calculate to only show 6 digits in the result.
2. Calculate the result of "1/3", which should be "0.333333" {6 significant digits}.
3. Calculate the result of "1e4", which should appear as "10000" {5 significant digits, so to speak}
4. "1000.119" results in "1000.11" {6 digits shown, although an interesting truncation.}
5. Calculate the result of "1e5". This appears as "1x10⁵", not "100000", which has 6 digits in it. Is this correct, or are we refusing to show an extra digit for integer numbers where we would do so for decimal numbers?
