Can anyone explain why I get a double when I pass the TypeName function a value from a single array? This code produces:

java.lang.Double
java.lang.Float

1 2 3 4 5 6 7 8 9 10 11	Dim x(0) As Single Dim y As Single Public Sub Form_Load() x(0)=0 Debug.Print(TypeName(x(0))) Debug.Print(TypeName(y)) End Sub

Hey there,
I don't know if it is intentionally meant or a mistake, but I found this in the VBA tree of the framework:
svn\Framework\src\VBA\VBArray.java

Source code

...
	public static VBArraySingle createVBArray(float[] val) throws Exception {
		return (new VBArray(val));
	}
...
        public VBArray(float[] val) throws Exception {
		setBound(0, val.length-1, false);
		for (int i = 0; i <= val.length-1; i++)	setValueDbl(i, val[i]);
	}
...
	public void setValueDbl(int Index, double Value) throws Exception {
		setValue (Index, new Double(Value));
	}
...

So we got a float being passed to setValueDbl(...) !!
