Scientific Notation Bug / Format Bugs:
Many OBS applications save cells with long numbers in a loose scientific notation format, this means any cell with a long, float, or double length number will be transformed into a relatively close but not correct scientific notation.
Example:612205820123 becomes 6.12206E+11 but so does any number of the same length if it starts with 6122058. This effectually destroys tracking numbers that do not include letters for example (FedEx).
Easy Solution:
The real number is saved as an office:value attribute attached to the table cell. If a office:value attribute is found on a table cell we simply need to use that value instead to avoid format bugs like this one; as well as any other bugs I may not have found yet, after all they (the OBS standards people) created the office:value attribute for a reason.
PS:
@nuovo - It seems pull request are going unanswered. I don't mind taking over this repo if you don't have time?
