Why would you assume iOS, not being the cheap option for a smartphone, would choose to emulate a cheap calculator? There were non-cheap calculators in the 1980

Why would you assume iOS, not being the cheap option for a smartphone, would choose to emulate a cheap calculator?
There were non-cheap calculators in the 1980s, too, that did proper evaluation. The ones I remember had keys for parentheses, though, allowing you to enter, for example
(3 + 4) * 7 =
to get 49.
For an example see the TI-25 at http://www.datamath.org/Sci/Slimline/TI-25.htm http://www.datamath.org/Sci/Slimline/TI-25.htm
- SoftTalker 2y agoWell I was responding to a post about "really cheap calculators" not non-cheap ones or iOS ones.
- kevin_thibedeau 2y agoThe point is, precedence following expression evaluation calculators starting from the 80s have always shown you the expression. No expression and no parentheses buttons (accumulator stack) implies a simple accumulator based design.
- Retric 2y agoThe app did have parentheses buttons, depending on rotation you’d get simple or scientific UI. Rotation changing how the calendar handled order of operations seems even less intuitive to me.
- pasquinelli 2y ago> Why would you assume iOS, not being the cheap option for a smartphone, would choose to emulate a cheap calculator? i'd assume that because the ui for the ios calculator app is the same as the ui of a cheap calculator. not sure i would ever consider the platform that app is running on.
