High accuracy calculator?
I'm looking for a high accuracy calculator that can deal with square roots to at least 20 places.
Anyone know of one? (If it is downloadable I need it mac friendly, sorry)

Historically, UNIX supports the arbitrary-precision "bc" utility:
$ bc
scale=40
sqrt(7)
2.6457513110645905905016157536392604257102
scale=60
sqrt(7)
2.645751311064590590501615753639260425710259183082450180368334
I don't know if the underlying Berkeley Unix on the Mac
has this installed or not.
If not, you can download the source from
ftp://mirrors.kernel.org/gnu/bc
You might be able to find the binaries if you browse around.
