You, sir, are the one who needs to go back--specifically
to zPOPs page 9-3:
please :-)
- look into wikipedia about the meaning of hexadecimal
- HPF magnitude is the product of the significant and the radix powered to the
exponent
the significant is a sequence of bits
the representation table in 9-6 shows what happens when you divide
(1 - 0.5 - 1/64)
the table does not use a hexadecimal representation
if you change the exponent in an hfp by one, you need to shift
the signicant by four bits to roughly get the same number (~
rounding/overflow)
thus it seems convenient to think about the radix 16 significant as a
sequence of hexadecimal numbers (which would then be shifted by 1)
- =X'ABCD' in BAL is still a representation of 16 bits.
