Just noticed there is one little gotcha. There is a scale command to say
how many digits of accuracy you want bc to do. It defaults to 20 but
that actually means the last digit will not neccissarily be correct. For
example, I did
4*a(1) which gives you pi but noticed the 20th digit was actually wrong
and not just rounded wrong. It showed the 19th digit as 4 when it should
be 6. Yes, for a while I memorized another digit of pi for each birthday
but stopped that silliness after 22. It was a moment of geekness.

If you're going to go that route you might want to pop up an OSX
terminal and do man on bc or dc which are arbitrary precision
calculators that work from a command line.

Hi there,
I gave up on built in calculators and now remotely connect on my
Linux box to use Qalc.
I am sure qalc can be installed on a Mac with no difficulties.
Qalc uses a command line interface.

It's called CalcMadeEasy Free and there's also the pro version.
They're working on the ios version and as soon as they're done,
they'll provide accessiblity, or moreso label the buttons.

Hi Chris,
Thanks for that one. Will be checking it in detail later this week.
I found another one with a note taking part where you can paste
past calculations or parts of it and plug it back into equations.
The issue is that all the buttons are unlabelled :) The devver was
forthcoming in rectifying this so good, but i need an immediate
solution so your suggestion might stick once i've understood the
layout
Thanks again

I don't think the built-in calculator will do it. The only Deg
button is just to switch modes from degrees to radians. There are
a jillion calculators in the app store so you might want to take
a poke through there. The LXVII calculator is one of those HP RPN
calculators which should do the trick. Every button has three
additional functions beyond its stated feature but on the 1
button there were R< and>P functions. If I left VO focus on
there for a few seconds it read the help text saying it was
rectangular to polar coordinates. On the third row of buttons are
three unlabeled buttons which are the f, g and h buttons (which
also read in the help text if you wait). They activate the
secondary functions written in different colors. So the g button
says it activates the blue functions which VO-A actually says are
turquoise, which would be the>P secondary function on the 1 key.
The f key activates the
yellow functions which VO actually reads as 'a shade of
merliwood" or something like that. So that would be the R< on
the one key. I also noticed that it didn't announce the values in
the display at the top without my moving VO focus there so I set
up a hotspot VO-shift-1 and then turned on monitoring of the
hotspot VO-Command-shift-1.
Hope that makes some sense.

Hi All,
The mac os calculator either has some serious performance
problems and doesn't have what i need or it's my perception that
wants everything to be extra zippy, and it does in fact have
what i want. But the question i have needs clairifcation before
i endeavor for an alternative solution:
With the current default calculator, i have to do some tedious
work before getting results i want, ie for changing values from
rectangular to polar forms when doing complex numbers.
Normally there's a rec deg function available on all scientific
calculators but on this one, i have to manually enter the values
which is a complete drag and annoyance.
Can anyone please tell me if there is in fact a way to do this
and i'm missing out on something somewhere?
Best regards,
Yuma
