'' Operator Does Not Support Floats?

Dim x As Integer = 1.8 1

Error:

Option Strict On disallows implicit
conversions from 'Double' to 'Long'

What Long??

EDIT:

Apparently Visual Basic attempts to convert any floating-point numeric expression to Long. OK, this part is clear.

Now, I can use the

CType((Math.Round(myResultingSingle)), Integer)

but what for MSDN tells that operator supports all the types if in reality it supports only Long as expression1 ?!...
