Re: (SQRT 0 1i ) ^2
Rounded to 10 places "when it was done"? If you round to 10 places after every operation, you'll get 1 / 3 = 0.3333333333, then after multiplying that by 3 you get 0.9999999999, which is still not 1. The kind of magic you seem to be looking for would require the calculator to know that it...

Re: (SQRT 0 1i ) ^2
What would be nice, though, is some indication whether a number displayed on screen has been rounded, as can be seen by using the SHOW function. When one divides 1 by three, then multiplies the result by three, the display looks like an integer value. The RND function works in all display modes exce...

Re: (SQRT 0 1i ) ^2
Brianetta, let's play a game; You are a computer, that can calculate with 1 digit and four decimal places. First you get the job to calculate 1 / 3: That results in 0,3333 Now you get the job to calculate 3 * 0,3333: That results in 0,9999 No errors occoured, but due to rounding and limited preciss...

Re: (SQRT 0 1i ) ^2
Your only error, fault, ... whatsoever: You bought a calculator and complained . I would like to appeal this sentencing on the grounds that I did not complain. Calling something a bug is not a complaint in my understanding. Like I said, some bugs we accept and work around, but we do need to be awar...

Re: (SQRT 0 1i ) ^2
That's true, of course, but I don't work in the field of applied mathematics. I bought a calculator.

Re: (SQRT 0 1i ) ^2
I do, but I also accept that some bugs can't be easily fixed and must be worked around instead. It's worth understanding them. For the expression X, dup, sqrt, sq, minus; X=0? is "Yes" for 1, 2, 4, 6, 8 and "No" for 3, 5, 7. That's unexpected, and affects program control. Pretty ...

Re: (SQRT 0 1i ) ^2
I'm pretty sure this counts as a bug, just one that is far too expensive to fix. We've instead learned to accept it.

Re: (SQRT 0 1i ) ^2
Taking the square root of a 15 digit integer, then squaring the result, will usually show a loss of precision.
