Just to be clear, I was referring to 'd' support for the existing identifiers when they handle the notation. For reasons I describe in my other post, I don't think it's a good idea for the new integer-only identifiers to try to support the approximation of this notation, since the approximations of 1.23e2 style of fractions can contain whatever rounding error comes from the source, which wouldn't be from mIRC because I'm not aware of mIRC itself creating this notation
