[Octave-bug-tracker] [bug #38974] strings package: base64decode retains trailing zeros

[Oliver Heimlich]

Follow-up Comment #7, bug #38974 (project octave):

I did a major review of the function's code and the bug is now fixed in the
repository
https://sourceforge.net/p/octave/strings/ci/db1ee7036df04061b20c51dc10545993ecf4a183/

As for the base64_* functions in core: base64_encode is already good for
general use and a valid replacement for this packages function. Allowing
strings as parameters would be a bonus.

However, base64_decode should be changed and decode into uint8 vectors by
default. These could then be typecast into binary64 or string or whatever by
the user. To decode into binary64 is not very userful, because it limits byte
sizes to multiples of 8. Having an optional type parameter for base64_decode
would be a bonus, but should not require a lot more code than calling typecast
in most cases.
