Bitwise Shift Left '<<'
Syntax
Assignment Variable = Variable << Shift_Amount
Overview
Shifts the bits of an integer value to the left a specified number of places. Bits shifted off the left end of a number are lost; bits shifted into the right end of the number are 0s. Shifting the bits of a value left n number of times also has the effect of multiplying that number by two to the nth power.
For example 100 << 3 (shift the bits of the decimal number 100 left three places) is equivalent to 100 * 2^3.
Operands
Variable can be a constant, variable or expression that holds the value to shift. Shift_Amount can be a constant, variable or expression that holds the amount of shifts to perform. Assignment Variable can be any valid variable type.
Example
Device = 24FJ64GA002 ' Select the device to compile for
Declare Xtal = 16 ' Tell the compiler the device will be operating at 16MHz
Declare Hserial_Baud = 9600 ' USART1 Baud rate
Declare Hrsout1_Pin = PORTB.14 ' Select the pin for TX with USART1
Dim MyWord as Word
Dim bLoop as Byte
PPS_Output(cOut_Pin_RP14, cOut_Fn_U1TX) ' Make Pin RB14 U1TX
MyWord = %1111111111111111
For bLoop = 1 to 16 ' Repeat with bLoop = 1 to 16.
HrsoutLn Bin MyWord << bLoop ' Shift MyWord left bLoop places.
NextBitwise operations are not permissible with floating point values or variables.
All left bit shifts are unsigned, regardless of the variable type used.
