Microsoft® JScript™ << Operator | Language Reference Version 1

See Also

##### 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 has a value of 56 because 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, see the Operator Behavior table.
