Hi,
One way is to do the following:
1. Export the table for backup purposes
2. Create a temp table containing the primary key and column to be altered.
3. update original_table set number_column=null;
4. alter original_table <table_name> MODIFY (column(3,2));
5. Update column from temp table. (Assuming all the data in temp table
will go in number(3,2) format.
