I haven't read the whole thread but I think it is important that you understand the underlying cause of the problem:
(a) Parameter.Value is an *object* so will accept whatever type you throw at it.
(b) You need to be aware of how numerica literals are cast:
param.Value = 0 ; //integer
=0.00 //double
=0.00m //decimal
(c) Finally understand how C# types are mapped to SQLTypes - see "Specifying parameter datatypes" here:

If you are clear on the above then you should be able to avoid this type of problem in the future....
