I don't want to start a philosophical discussion, but I'm puzzled: What constitutes "correct" behaviour in this case? Are you saying that 'correct' would be something like: 1 printStringHex '0F' and 1 hex '16r01' ??

Hello all,
I get a strange behaviour while trying to print hexadecimal values of a string.
Context: I get a SHA1 hash from a binary stream, store it into a string, and I want to display that string (using asHex).
Problem: for values inferior to 16, the leading zero is ignored. (15 -> 'F' instead of '0F').
indeed printStringHex prints F instead of 0F 15 printStringHex 'F' 15 hex '16rF' Geoffroy could you add a variant that produces the correct behavior with some tests?
I could modify SmallInteger>>printStringBase: to always include the leading zero, but I fear I'm going to break a lot of code doing that. Is there a better way to fix my problem? apart from using directly the following: aStream do:[:val | val printStringBase:16 nDigits:2]
Best regards,
