That doesn't make any difference for numerical stability.
This is a property of an algorithm, not of the language.

It's probably gonna be silly question, but after short analysis i don't
see, what could be broken in this demo snippet, when float is standard
single-precision 32bit type.
I omit first case, as optimizing compiler could just optimize it to
just =1; though it could do it in second case too... (as a

Wholly greetings!
QjackCtl 0.5.5 (black-friday'18) is released!
QjackCtl [1] is a(n ageing yet modern, not so 'simple' anymore) Qt [2]
application to control the JACK [3] sound server, for the Linux Audio
[5] infrastructure.
Website:
https://qjackctl.sourceforge.io
http://qjackctl.sourcefo
It could be lame question, but still... is it possible, that some
implementations (compiler/hardware) will print 1? (even 64bit doesn't
hold 20 decimal digits).?

Depending on context and the maths, the difference may not matter at
all, or may be off completely..
float a = (1 + 1e20) - 1e2
