Dave --
Yup, that's another one!
I get the following on my 33S (CNA4134082)
Key in -14.2900 Press HR HMS See -14.2820 (INCORRECT! -- should be -14.2900)
Key in 14.2900 Press HR HMS See 14.2900 (CORRECT)
I tried a few others. The consistent factor seems to be incorrect reconversion back to H.MMSS from H.DDDD, of a negative H.MMSS value where,
MM = 3n+2 (integer n = 0 through 19); and
SS = 0.000
In other words, for any negative H.MMSS with |MMSS| exactly equal to
.02, .05, .08, .11, .14, .17, .20, .23, .26, .29, .32, .35, .38, .41, .44, .47, .50, .53, .56, or .59
->HR ->HMS will yield |MMSS| = .0120, .0420, etc.
Weird! (And unacceptable -- none of the HP-designed calc's make this mistake.)
It seems that certain internal representations of numbers are not being handled in a consistently correct fashion.
