1.Try convert some fixnum number directly to bson_int64
require 'bson'
s=102.to_bson_int64(102)
2.Check s.bson_type

Actual: It returns '\x10'.

Expected: Since the method is called to_bson_int64 - it should work as it names and set the bson_type to '\x12'. In my particular case, our dev guys wrote their own c++ bson parser and for some number values always expect to have bson_int64on server. So far I have to use extremely big numbers for those values, but it looks ugly.
