Hi,
for a list of all functions/features of th 49G please take a look at www.hpcalc.org
For the HP-19BII functions: I doubt that all functions of the 19BII are included in the 49G. Why should they?
The 19B series are business calculators, whereas the 49G is a scientific calc.
Please don't mix calc power with functions count.
The number of functions isn't necessarily equal to the power level of a machine.
The 4x series has much more functions than the 19B series,
but out of the box, the 19B(II) can be much more powerful for financial calculations.
Of course you can expand the 4x series with financial software.
On the other hand, you can turn a 17BII into something like a scientific calc by programming SIN,COS, etc.
(This is described somewhere here on this site)
