AudioUnit parameters broken with recent commit

[daniel]

This is a result of a longer journey of changing back and forth of the behaviour of the String (double, numDecimalPlaces) constructor, as I understand it.

It started with this feature request:

String constructor: specify significant figures?

Could we get an additional String constructor to specify the number of significant figures in a float value (as apposed to decimal places). When using certain values with a large range - such as frequency - it’s nice to be able to keep the displayed values a consistent length (20.000, 200.00, 2000.0, 20000). At the moment I can manage this with a rather ugly if-else block and setting the String’s decimal places based on the value but it would be nice to be able to do this in one line.

and concluded in the behaviour being changed a few times, until it was thought all parties are happy:

String breaking change

Yeah, apologies for this one being a bit of a messy change. The problem was that it was never intended to work the way it did, but a test had somehow been added that checked for the wrong result, which made it all look legit. The function as it stood was full of edge-cases where its behaviour would be ambiguous or problematic - it really wasn’t very good, and IIRC the reason I changed it was because it caused bizarre problems in something else I was working on. We discussed the fact that it wou…

Seems to be difficult to create a coherent solution with full backward compatibility. It probably needs to be deliberately broken, so every user has to choose the behaviour that suits his use case.
