Language Reference 

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

Syntax
result <<= expression

The <<= operator syntax has these parts:

Part Description
result Any variable.
expression Any expression.

Remarks
Using the <<= operator is exactly the same as specifying:

result = result << expression

The <<= operator shifts the bits of result left by the number of bits specified in expression. For example:


var temp
temp = 14
temp <<= 2 

The variable temp will have a value of 56 as 14 (00001110 in binary) shifted left two bits equals 56 (00111000 in binary). Bits are filled in with zeroes when shifting.

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