Hi All,

Thanks,

Check out the ruby.h header file. Look for macros for converting C
numeric values to Ruby numeric values, such as LONG2NUM/NUM2LONG and
LL2NUM/NUM2LL.

Hi Tim,

LL2NUM/NUM2LL did the job. Since I did not see this in the README.EXT of
the 1.9 code base I assumed it did not exist. Next time I will read the
header files better.

Thanks so much!
