That's right, the 42sx has two stack levels. You'll never forget where you are in a calculation or what is on the stack again. The 42sx naturally supports the entire gamut of stack operations with Rv, R^ and x<>y in their natural positions on the keyboard. Plus we've added the never before featured functions Rvv and R^^ for two position rolls.

I was hoping for a one-level stack! When memory (mine, not the calculator's) gets short, we must conserve all we can!

Quote:One red dot greatly increases the value of those calculators possessing it. The 42sx has two red dots. One is used to indicate on, the other off. We saved space by putting both of them in the same location. It is so natural and intuitive you'll wonder how you managed so long without.

I am going to be selling after-market red dots (not calculators, just red dots) on TAS. You'll be able to apply them to all HP models including the original HP-35! Unscrupulous vendors may try to pass them off as original red dots but I can't control that.

Quote:The 42sx strives for numeric accuracy throughout its thousands of functions. That's why we've made sure the original 2.02 results are there. Trigonometric functions perform excellently except around multiples of fifteen degrees where all digits are lost.

I never cared for those values anyway. Good work, HP!

Quote: We've included hyperbolic and elliptic functions. Three different ζ functions, factorial, Γ, Ψ and six other Greek alphabetic functions.

Why limit yourself to Greek letters? I'd like to work with Hebrew letters א-null (aleph-null), anyone?, and Chinese characters (how many functions would that be?)

Quote:We also support complex numbers, that's right numbers on the 42sx can have a decimal point in any position. We think this is amazing.

I'd like multiple decimal points in a number. As with my meds, if one is good, more must be better, right?

Thanks for a great laugh!
