Good point and I support the change in naming. We should have seen this earlier. However, we do also support decimal representation of irrational/transcendental numbers. I think you mean "finite decimal approximations of real numbers". We do not support complex numbers (and I do not see a real use case for them!). Not knowing the details of how Java handles floating point numbers, but I also assume that this is a 32 bit decimal representation, which further restricts the length of the number which the regex does not really account for. > Yes, I think maybe integer is the way to go, since whole numbers is > not clearly defined.

Not being an authoritative source on this, I think we should stick with positive and negative integers and be sure they are explained well in the help. I think if we need a set of numbers, which include 0 and positive integers, we should use "Natural numbers", or allow zero to be included in "Positive and negative integers", but be sure it is well explained in the manual. >> As for the support for scientific notation, I am not necessarily >> opposed to it, but think we need to stick to the more strict regex >> validation. > > I think maybe supporting e-notation but restricting it might be more > confusing.. ? not sure here... maybe just plain decimals is OK. > Well, if we support it, we need to be sure it is valid and I personally do not trust !NaN. I see no real need for it and unless people are asking for it, I suggest we simply not allow it.
