Not TeX, though. TeX computes in "sp", which are 1/65536 of a TeX point;
the wavelength of visible light is a few sp, so errors at that level
are literally invisible.

Indeed, and what's so annoying is that there's no damn reason for it.
Laser printers, even those sold in the US, universally accept A4 paper;
supply catalogs sell it, and not even at a premium price....
North America could literally go over to A4 tomorrow and hardly anyone
would notice. Except that then when I print an A4 document from
Ghostscript my printer wouldn't throw itself off-line waiting for me
to load the (nonexistent) A4 paper.
