Nothing -- if you take the time to _read_ the mail to which you're
replying, before launching into a tirade, you might notice that I
actually pointed to "zmodload math/compfunc" and then using the float()
function.  I wasn't saying that zsh is not useful.

What has this got to do with it?  Is C an exemplar of good design, now?

Yet Another typeset flag.  There are already flags handling how
