JScript <<= Operator

Left shifts the value of a variable by the number of bits specified in the value of an expression and assigns the result to a variable.

Syntax: JScript <<= Operator

result <<= expression

Arguments: JScript <<= Operator

result

Any variable.

expression

Any expression.

Remarks: JScript <<= Operator

Using this 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 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, see the Operator Behavior table.
