Possible bug on HP50G with very large numbers

[Gil]

Always on a HP50G

1)280! gives
167... —> a correct number

And Log(167...) gives
69+Log(167...)

that is
69+496.22=565.22

which is a 566 digit
and that is correct.


2)281! gives
471... —> a correct number

And Log(471...) gives
69+Log(471...)

that is
69+498.67=567.67

which is a 568 digit
and that is correct.

3)282! gives
1329... —> a correct number

BUT Log(1329...) gives
69+Log(1329..)

that is
69+(exactly ?! 500)

which is a 569 digit
and that is clearly WRONG.

Strange isn't?
