function return and int()?

hello to all processers
I have a simple question on function syntax;
int test() {
return( int(5.5) );
}
void setup() {}
void draw() {
println(test());
}
Why this doesn't work, while
int test() {
int x = int(5.5);
return( x );
}
void setup() {}
void draw() {
println(test());
}
this works? any particular reason?
(sorry about the dumb question, I just want to understand the concept behind this...)
Thanks to all!

one syntax that always work when "type-casting" is, e.g:
Code:
like in
Code:int test()
{
return (int) 5.5;
} |

concerning the "int(something)" syntax, i think it's not in the java language, but rather a helper provided by the processing preprocessor (the same way: assigning a value of 5.5 instead of 5.5f to a float will work in processing but not with a standard java compiler...)

thanks Ariel!
by the way, you just made me realize that if I erase the parenthesis out of the return statement, it works... I'll start to use the other syntax anyway. Real Thanks!
