Hi,

For my accounting I like to use ScaledDecimal, knowing it is just a fraction with a scale.

I just stumbled upon the following:
0.1s * 0.5s. "0.0s1"

The underlying fraction is correct (1/20). However, the scale is 1, which surprised me. Shouldn't the scale be 2?

In VA Smalltalk which I use for accounting as well the multiplication results in 0.05s2, which I had expected. (It prints as 0.05, though.)

Fraction>>#asScaledDecimal even has the needed code:
"Convert the receiver to a ScaledDecimal.
	If there is a finite decimal representation of the receiver, then use the exact number of decimal places required.
	Else, use a default number of decimals."

(1/20) asScaledDecimal. "0.05s2"

Some other strangeness:
3s scale. "0"
3 asScaledDecimal scale. "0"
3s asScaledDecimal scale. "8"

ScaledDecimal>>#asScaledDecimal should probably just return self.

What do you think?
