Weird character in the VBA for dummies book...

[adamjohnson182]

I'm brushing up on my VBA and came across the following example in the VBA for Dummies book:

Sub ShowCubeRoot()
Num = InputBox("Enter a positive number")
MsgBox Num ⁁ (1/3) & " is the cube root."
End Sub

What's that character before the (1/3)???? It looks like a backward Lambda?
