This is all from memory, so take it with a grain of salt - The 'Classic' 3000 systems used a proprietary (i.e., non-IEEE) format for floating point. The PA-RISC systems use IEEE 754 floating point 'natively'. TurboIMAGE databases (which may be what you're referring to when you say 'how numbers are stored' provides both an IEEE format and a Classic format. I have no idea the relative usage of these formats in the 'real world'. There is also an intrinsic (HPFPCONVERT?) to convert between the two formats.
