Re: Storage of numeric data

Peter,

You will get out whatever you put in with just regular NUMBER type. Format like number(4,3) only controls/constraints the number you write into this column. You could use it, if you know in advance that you will never try to write bigger numbers, or with more significant digits, or you want to limit numbers written into the column to this format and get error message otherwise.
