Where I'm stuck is how MariaDB decides between scientific and regular decimal notation. The number of significant digits, their position relative to the decimal point, and the target column length all seem to play a part, but I can't deduce exactly how.
This is done in our my_gcvt() function. Its goal is to minimize the information loss, given the limited target column length. There are different cases to consider, comments in the function explain some of them. Regards, Sergei Chief Architect MariaDB and security@mariadb.org
