I looked at other zsh builtin functions and couldn't find any others that could be moved to common. I found log, but the log on my system was for calculating logarithms (log.3), and not actual logging (log.1).

Did you check the command, or just the man page? log.3 documents a C function, not a command.

@acuteenvy I also checked the command itself, this is probably a better page for the documentation. It can be used like this:

(( result = log(10.0) ))
print $result
