Numeric types precision

[Ян Программист <we...@gmail.com>]

Problem: numeric type conversions, for example float to double, does not
provide a way of normalizing column size(digit count) in a automatic way

Solution: throw program exceptions, while tuning, and catch those, doing
necessary strategy switching: either table schema would be changed, either
cell value would be changed. Adding additional tables with specific numeric
precision is also possible. The most interesting thing - to populate tables
with few columns with same data type, but different precision.

Wanted to hear those who had experience with such things. John
