7.4.10 <<= Operator

Used to the bits of an expression to the left.
 

Syntax

result <<= expression

Arguments

result
Any variable.
expression
Any expression

Remarks

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.
