Yes, that was the OP's request. But we do problem posers no great favor, when they appear to be laboring under misconception(s), by unquestioningly answering only their bare questions when it is apparent they probably need to reframe the issues and reconsider what the problem really is. So, "What is wrong with storing 0.0?" is very apropos, whereas the suggestion that '0.00' be stored (as TEXT) has a good chance of mystifying somebody who can confuse 0.00 with 0.0 (which are floating point literals in this context.)
