Left Shift Assignment Operator (<<=) (Windows Scripting - JScript)

  • Article

 

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

Syntax

result <<= expression

Arguments

  • 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.

Requirements
