Subject: BigDecimal and BigMath

Hi,

I am developing an application that requires very large numbers, so I am
using BigDecimal.

I wanted to use atan, and saw that there was a bigdecimal/math, which allows
you to use an atan that supports BigDecimal. However it seems faulty. It
says you cannot pass a value for x that is greater than 1 or less than -1.
As far as I know, there is no such limit for the arctan. Also there is no
asin or acos.

Are there any alternatives that support a bit more in terms of trig
functions?

Also, I wanted to ask whether there was any practical limit to the precision
of a BigDecimal number? I'm looking at numbers in orders of magnitude
between about 15-25 at most.

Thanks,
Brandon
