== ~ (Bitwise NOT)==

<p>The bitwise NOT is represented by a tilde (~).</p>
<p>The bitwise NOT is a three-step process:</p>
<OL><LI>The operand is converted to a 32-bit number.</LI><LI>The binary form is converted into its one"s complement.</LI><LI>The one"s complement is converted back to a floating-point number.</LI></OL>



<source lang="javascript">
var iNum1 = 25; //25 is equal to 00000000000000000000000000011001
var iNum2 = ~iNum1; //convert to 111111111111111111111111111100110
alert(iNum2); //outputs "-26"</source>

<p>The shift left operator looks at the integer to the left of the operator as a 32-bit binary number.</p>
<p>The number of positions specified by num2 shifts all the bits of num1 to the left.</p>
<p>As the bits are shifted to the left, zeros are filled in on the right.</p>
<p>Because the number can only be 32-bits long, the extra bits on the left are lost.</p>
<p>The 32-bit binary result of the shifting operation is converted to an integer value and returned from the shift left operation.</p>
<p>The result generated from the shift left operator can be quickly calculated by multiplying the number by 2 raised to the x power, where x is the number of positions shifted.</p>

== >> (Shift Right with Sign)==

<p>The shift right with sign operator looks at the integer to the left of the operator, num1, as a 32-bit binary number.</p>
<p>All the bits in this number are shifted to the right by the number of positions specified by num2.</p>
<p>If the original number is positive, zeros are added to the left side of the binary number.</p>
<p>If the original number is negative, ones are used.</p>
<p>The extra bits on the right are lost.</p>
<p>The 32-bit binary result of shifting operation is converted to an integer value and returned from the shift right with sign operation.</p>
<p>The result generated from the shift right with sign operator can be quickly calculated by dividing the number by 2 raised to the x power, where x is the number of positions shifted. Discard the remainder.</p>

<p>All the bits in this number are shifted to the right by the number of positions specified by the integer to the right of the operator.</p>
<p>As the bits are shifted to the right, zeros are filled in on the left, regardless of the sign of the original integer.</p>
<p>The extra bits on the right are lost.</p>
<p>The 32-bit binary result of this shifting operation is converted to an integer value and returned from the shift right zero fill operation.</p>
