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

See Also

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