result

Any variable.

expression

Any expression.

Using the <<= operator is exactly the same as specifying:

	Copy Code
result = result << expression

The <<= operator shifts the bits of result left by the number of bits specified in expression. For example:

	Copy Code
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.
