10.4: Be aware of a Calculator widget bug
Authored by: pantera on May 24, '05 12:02:21PM

As others have pointed out, this clearly is not a bug. The calculator widget both visually and in its behaviour is a simple step-by-step calculator.

If you want to enter complete formulae (with parentheses, and the usual operator precedence) you can use FormulaCalc. As mentioned earlier, using RPN notation with "RPN calculator" is a viable alternative.

I find the interface of the calculator app in Tiger to be rather bad, as there is no clear visual feedback to the fact that it is evaluating a complete formula, and not doing step-by-step processing. Calculators behaving that way usually have an entry line showing what you have typed so far, which calculator.app is lacking. Only the paper tape shows you (afterwards) what has actually been done. This is particularly inconsistent with the fact that the basic interface has no parentheses.

As I have consistently pointed out, this is most certainly a bug. Math doesn't change because developers are lazy. Now, if they want to clean up the interface, I'm all for that, but left to right is not correct under any circumstances.

No one is claiming that math changed. All that is being said here is that the calculator is just calculating one operation at a time. This is standard and expected behavior of calculators of this sort. The only non-graphing calculator I have ever seen that used order of operations was one with advanced features like parenthases.

Standard scientific calculators you get in year 8 use BIMDAS.
