JScript Bitwise Left Shift Operator (<<)

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

result = expression1 << expression2

result

Any variable.

expression1

Any expression.

expression2

Any expression.

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 as 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.
