```oh, sorry, i meant how to get the 0x0A27 out of two bytes
a = 0x27 and b = 0x8A

actually, in my script, i am not using the hex values at all, i have
these because they are examples in the documentation of a machine i am
talking to. i am actually using ord(a) and ord(b) to get digital
values of the numbers

so, i guess a better question is how to get 2599 from the ord(a) and
ord(b), how do i put the two bytes together to make one number?
