Re: it's not NULL, then what is it?

Hi Tom,

It is redhat linux running on Dell hardware.
uname -a returns:
Linux vixen.egcrc.org 2.6.9-78.0.1.ELsmp #1 SMP Tue Jul 22 18:01:05 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

Good question. So far as I can see these must be some value that
sprintf() is printing as spaces; but not NaN and not Infinity because
float4out checks for those first. I would argue that this must be
a bug in sprintf. What platform are you running on exactly? And
for that matter, what PG version is this?
