HP45 stack logic problem

[Jake Schwartz]

Quote:Know here's where the problem comes in, if invoke the y^x key say 3 2ndf and press y^x (thats 35^3) and the answer is displayed correctly however if you roll the stack down you find
30=t
30=z
30=y
answer displayed correctly in x, notice t contains 30 and it would seem the stack has gone the wrong way, the stack should be
0=t
0=z
30=y
answer displayed correctly in x

Hi,

If I followed you correctly, once you keyed the "3" in order to compute 35^3, everything moved up a level and the zero in t was replaced with the 30 from z. Then the y^x would subsequently cause the 30 in t to be replicated back down into z. Had the stack been one more level high, the zero would have been retained.
