Shifts left and assigns a value to a variable

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 )

Usage

` lhs shl= rhs

`

Parameters

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.

Examples

start GeSHi

Dim i As Integer
i = &b00000011   '' = 3
i Shl= 3         '' = i*2^3
'' Result: 11000          24            24
Print Bin(i), i, 3*2^3
Sleep

end GeSHi
