And here is the same code in unit/module form with tables commented out: The possible table lookups/optimizations are left in in case I or any one else wants to test those ;) // *** Begin of Module Code *** unit UnitStringToUint64_version_003; interface function TryStrToUint64( S : string; var Value : Uint64 ) : boolean; implementation { Skybuck's TryStrToUint64 conversion

Hello, Sometimes I google for my own code and then it sucks if I one can't find it or too it's incomplete. So one more time the complete code as it now is, all 3 versions embedded. Version 0.03 is now active... big 1600 bytes lookup tables still active but those could be commented out. Maybe somebody else could write a nice benchmark program for it ?
