Hi.
This is a bug, right?
% zcalc
$1 > 122114.671875
122115
$2 >
(I've received id as the result of 125045424.0 / 1024.0)

What do you think is the bug? That it's rounding to six decimal places?
As it says in the zshcontrib manual, that's the normal effect of the
printf %g format. If you want the output to have raw format, which
might show more decimal places than the actual precision, use :raw.

I meant significant figures, obviously...

Sorry, I confused it with %f.

I have to say it confused *me* working out what a sensible default was.
You really want something like a really calculator does, but that's (I
suppose, I don't know what the firmware looks like) presumably taking
some arbitrary number of significant figures that they've worked out
will be correct for the precision used internally. For a slightly more
general purpose programmer's tool like zcalc, sticking with the standard
formats available seemed a more obvious thing to do. %g looked like the
least worst option.
