RE: Unexpected Feature on HP-22
This is interesting as I was working on the "scientific notation" article in Wikipedia recently (which does not cover this implied input method so far). Brings up a number of questions (regardless of brand):

- First calculator to support number display in scientific notation (with or without a dedicated mode)?
- First pocket calculator to support number display in scientific notation (with or without a dedicated mode)?

- First calculator to support some kind of "enter exponent" key?
- First pocket calculator to support such key? (HP-35 in 1972?)

- Origin of the E-notation (like in -1.23E-45)? (The first occurance I could find so far was in FORTRAN II as of 1958, but the notation might be even older.)

Greetings,

Matthias
