You can look at casting as something you use to help the compiler when assigning values to variables that aren't obviously fit to contain them (like an int for a float variable of a Foo for a Bar variable) - that's what's common with copying floats and object references. For learning more about it you can look it up in a Java or C manual, though they'll contain a bit more than what's needed in ChucK (which doesn't have a lot of primitive types for starters). I'm a Java fan, so I'd go here: <a href="http://java.sun.com/docs/books/jls/third_edition/html/conversions.html#5.5">http://java.sun.com/docs/books/jls/third_edition/html/conversions.html#5.5</a><div>

Hi there,<br>

<div>> Hmm, you shouldn't have to cast from a subclass to its superclass, should<br>

<br>
</div>Well, this is my feeling as well. A foo is-a spam. The object<br>
reference should work fine this way...<br><br></blockquote></div><div><br>I agree. Back when I was starting out when classes and so on I did feel that this functionality was actually implied by the docs. I wonder whether that was intentional and that's actually meant to be how it should eventually work. This is one area where I do feel that the current docs need work. For one thing the "$" operator is only documented in how it casts from float to int, which is in and of itself a exception in that it loses information, unlike other forms of casting that need not lose information.<br>
