Logical and '&'

Syntax

Assignment Variable = Variable & Variable

Overview

The And operator returns the bitwise And of two values. Each bit of the values is subject to the following logic: -

0 and 0 = 0 0 and 1 = 0 1 and 0 = 0 1 and 1 = 1

The result returned by & will contain 1s in only those bit positions in which both input values contain 1s.

Operands

Variable can be a constant, variable or expression. Assignment Variable can be any valid variable type.

Example 1

Device = 18F26K40                    ' Select the device to compile for
Declare Xtal = 16  ' Tell the compiler the device will be operating at 16MHz
Declare Hserial_Baud = 9600          ' Set the Baud rate for HRsoutLn

Dim bMyVar1 as Byte
Dim bMyVar2 as Byte
Dim bMyResult as Byte

bMyVar1 = 0b00001111
bMyVar2 = 0b10101101
bMyResult = bMyVar1 & bMyVar2
HRsoutLn Bin bMyResult                ' Display the AND binary result: 00001101

Example 2

Device = 18F26K40                    ' Select the device to compile for
Declare Xtal = 16  ' Tell the compiler the device will be operating at 16MHz
Declare Hserial_Baud = 9600          ' Set the Baud rate for HRsoutLn

HRsoutLn Bin (0b00001111 & 0b10101101)  ' Display the AND binary result: 00001101

Note.

Bitwise operations are not permissible with floating point constants or variables.
