0.0 when you assign to a double, for clarity?

[Peter Kasting, 2015/06/08 20:44:29]

I can if you really want, though I'm not a big fan.

As you sort of allude to below, "= 0" is fairly common throughout our codebase
-- "= 0.0" is exceptional.  And "= 0.0" implies to me that it was important not
to say "= 0", which is what I'd have normally expected the code to read; like,
maybe somehow "= 0" would result in a run-time value conversion of int to
double, or "0" alone wasn't precise enough.  Since neither is true, it calls my
eye to the code for a difference that doesn't actually matter.

ALl that said, my opposition to this is weak, so if you still think 0.0 is
better, I'll do that.

The WebRTC audio code is littered with float literals such as 0.f, but if that's
not the case in general then I'm happy to use just 0 here (since, as you say,
the compiler will not care either way---the only consideration is human
readability).

0.0 here too? (And in any more places?)
