>Likewise when we say "numerical issues", it's understood that we're talking about situations in which the usual approximation of real numbers by floating point representations breaks down.
Guys, try this in your desktop or mobile app calculator:
do square root of 2.
then subtract from it the result that you see on screen.
for me:
√2−1.41421356237
i get:
3.095048801E−12
i.e. not 0.
I discovered this on a physical Casio electronic calculator long back, and also verified it just now on a stock Android mobile calculator app.
