[Pharo-project] Another stupid question
This was just an example to play with since you asked for a #convertFromBase:to: method in your original mail and one cant provide such a method on Number. Your original request 11 convertFromBase: 2 to: 10 may work - but it wont work for hex values: FF convertFromBase: 16 to: 10 then FF would have to be a string. 'FF' convertFromBase: 16 to: 10 So having a #convertFromBase:to: on String is not to recommend (especially since the string has to be in a number format) and also not necessary. I should have added this to my mail as a warning. Just use (Number readFrom: self base: sourceBase) printStringBase: targetBase If necessary put it in a private helper method for conversion. May I ask why you require conversions between the different base systems? Working on a hex editor for Nautilus? ;) Bye T.

I have to implement a FTP server for a lecture, and the port is provided in a strange format (twice 8 bits). So I needed to change the port in base 10 to base 2, cut it into two pieces, then turn those pieces back in base 10 :)
Working on a hex editor for Nautilus? ;)
Is a hex editor a need ? :) Ben
Bye T.

Wait, wait, wait. You mean like #[16 45] ? What's wrong with Number1 := sourceNumber >> 8 Number2 := sourceNumber bitAnd: 255 ? Cheers, Henry

There is also sourceNumber asByteArrayOfSize: 2 1000 asByteArrayOfSize:2 #[3 232] Sven

Thank you guys :) I definitely feel stupid now :D Ben
