Operator Shl= (Shift Left And Assign)
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.
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
Sleep
`
