FAQ
Ah ha. Thank you very much Alberto. This should get me a lot further.

On a more general point. Given that you have written this, is math/big
might lacking some more functions. Do you, or anyone else, have an list
of functions that should be added?

This isn't my area by any means, but if it scratches an itch, I'll offer
to help.

For floor you have to use Float.Int()

I have Sqrt, Log and Pow implementations here:

DISCLAIMER: I don't guarantee correctness of the last decimal digit

It's not a real library, more like a few experiments (I'd like to see
at least Sqrt merged in
math/big, but not right now, it's not tested enough).

Hi,

I find myself trying to covert some Python code to Go which
uses arbitrary large numbers.
The original Python code takes the square root and floors the
result of one of these numbers.

But, looking at Go's math/big package, I can't work out how
square root one of these numbers. There doesn't, at first
glance, seem to be an arbitrary "pow" function. Likewise the
floor function.

As this isn't my usual area, I feel don't understanding
something fundamental. Does anyone have any pointers, or
packages, or example code that can point me in the right
direction?

Thanks

Owen
