Syntax

Declare Operator Shl= ( ByRef lhs As Integer, ByRef rhs As Integer )

Declare Operator Shl= ( ByRef lhs As UInteger, ByRef rhs As UInteger )

Declare Operator Shl= ( ByRef lhs As LongInt, ByRef rhs As LongInt )

Declare Operator Shl= ( ByRef lhs As ULongInt, ByRef rhs As ULongInt )

Parameters

Name		Description
`lhs`		The variable to assign to.
`rhs`		The value to shift
`lhs`		left by.

Description

This operator shifts the bits in its left-hand side (lhs) parameter a number of times specified by its right-hand side (rhs) parameter, and assigns the result to lhs. It is functionally equivalent to:

lhs = lhs Shl rhs

This operator can be overloaded for user-defined types as a member Operator using the appropriate syntax.

Note: Similarly to the operator '=[>]' (assign), the alternative symbol 'Shl=>' can be also used.

Usage

Example

Dim i As Integer

i = &b00000011   '' = 3

i Shl= 3         '' = i*2^3

'' Result: 11000          24            24

Print Bin(i), i, 3*2^3
