Hi, In message "[ruby-talk:03162] FixNum => BigNum transition" on 00/06/07, Robert Feldt <feldt / ce.chalmers.se> writes: |Any suggestions for an easy (and effecient?!) way to work with uint32's in |Ruby? I'm afraid there's no easy way to work with uint32 directly in Ruby. How about wrapping everything using uint32 in an extension library? C macro NUM2UINT() and NUM2ULONG() handle integer boudary checks. Just a suggestion. matz.
