For which models was 2^3>8?

Thanks for the great explanation, Dieter.

Just playing around, my MK-61, after a slight pause gives 7.9999993.
Doing [2] [ENTER] [ln] [3] [x] [e^x] also gives 7.9999993.

The 25C is more accurate, but similar, in that [2] [ENTER] [3] [y^x] and [2] [ENTER] [ln] [3] [x] [e^x] both give 8.000000002.

However, my 32E, 41CV and 15C, whilst giving [2] [ENTER] [3] [y^x] as 8.000000000, for [2] [ENTER] [ln] [3] [x] [e^x] they give 8.000000003.

Edited to add for Dave that my Sinclair Cambridge Scientific, which doesn't have the luxury of a [y^x] key, gives 7.9998.
