Integral numbers are not 'a computer engineering byproduct'.

It's hard to understand for someone who knows only mathematical
idiosyncrasies and who is also convinced that this should really be
more than enough for a lifetime. But that's not some kind of 'natural
knowledge' people just happen to have but systematically drilled into
pupils from a very early age, despite most of them won't ever have any
use for any of it insofar it goes beyond + - * /.

If you have to use something (like a particular programming language)
but you resent learning how to use it and rather make lofty excuses,
chances are that you are rather a lazy f*cker than a great philosopher
