Summary0006533: Decimal inconsistent to part 3 (and formula)
Description

In part 3 (8.54) it is described as
... The scale is the inverse power of ten that is applied to the unscaled value.

In part 6 is described as (missing the "inverse")
... The scale is the power of ten that is applied to the unscaled value

In the formula the "-" sign is mentioned.
For better readybility I would prefer a notation like "value * 10^(-scale)"

In any case - is it really a good idea if a defined scale of "-2" has to be specified to get a "10^2"?

Change Part 3 to match Part 6.
Needs 1.04 Errata

After investigating this issue the conclusion is that Part 3 and Part 6 both define scale as being an inverse power of 10.
However the description in Part 6 can easily be misinterpreted and should be updated to better explain the inverse power.
The use of the inverse power doesn't seem natural but after some investigation we found that Java defines the BigNumber type in this way also.
