Description
Shifts 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 has a value of 56 because 14 (00001110 in binary) shifted left two bits equals 56 (00111000 in binary).
