I thought about that, but inf needs to be supported at least for decibel
volume parsing, so I decided not to filter those out. Allowing them is
also less prone to bugs than allowing NaN, because this kind of range
checks behave as expected:
if (d < 0 || d > max_allowed)
If d is -inf or inf, that check works fine, but if d is NaN, the range
check doesn't fail as it should.
