I see the logic of that, but I also think that this is not how many users think when they want to know how to get results for 4/9. Note that division is a great stumbling block in middle school. They want
to know how to divide four by nine and don’t want to think about division and formatting as separate operations to be looked up in separate chapters. Perhaps they should think that way, but they don’t, and as Adenauer, modern Germany’s first chancellor, observed:
you have to take people as they come because there are no others. At the least the table 9.5 in 9.3 could have an NB about the problem of decimals in division, together with an example of how to do 4/9 in different formats, and a reference to the fuller discussion.

That would be the responsibility of the "Data Type Formatting Functions" chapter and the "to_char" function it describes. David J. |
