I'm building a C extension and have a "long long"
which I want to turn into a Bignum. Can anyone
point me to an example please? I've googled without
success.

Basing this purely on a random guess (based on reasonable assumptions about ruby) try:
LONGLONG2NUM()

Reasonable guess I suppose, except that doesn't seem to
be declared anywhere (ruby 1.8.1-11) :-(.

Thanks both. I have my extension working.

Kudos to Matz also - it's really easy to build these things :-).

Hopefully by now you've seen Daniel's more accurate response. (LL2NUM(x))
