Description
Used to shift the bits of an expression to the left.

Syntax
result = expression1 << expression2

The << operator syntax has these parts:

Part Description
result Any variable.
expression1 Any expression.
expression2 Any expression.

Remarks

The << operator shifts the bits of expression1 left by the number of bits specified in expression2. For example:


var temp
temp = 14 << 2

The variable temp will have a value of 56 as 14 (00001110 in binary) shifted left two bits equals 56 (00111000 in binary).

For information on when a run-time error is generated by the << operator, please see the Bitwise Operators table.
