Decimal's nextUp and nextDown ignore precision

[Martin (Martin R)]

Possible bugs of Decimal.ulp and Decimal.nextUp were mentioned here:

Why is Decimal.ulp greater than any decimal value itself?

Trying to find the number of decimals in a decimal number, I tried this in a REPL: 39> Decimal(0.01) > Decimal(1.0) $R28: Bool = false 40> Decimal(0.01).ulp $R29: Decimal = 0.010000 41> Decimal(0.01).ulp > Decimal(1.0) $R30: Bool = true This doesn't seem to work as expected. In fact, the ulp of even a small Decimal number, or a number with many decimal places, will still be larger than a very large Decimal number with no decimal places: 105> Decimal(string: "1.01")!.ulp > Decimal(string:…
