JavaScript | Math.clz32( )

The Math.clz32( ) function in JavaScript returns the number of leading zero bits in the 32-bit binary representation of a number.

Clz32 stands for Count Leading Zeros 32.

If the passed parameter is not a number, then it will be converted into a number first and then converted to a 32-bit unsigned integer.
If the converted 32-bit unsigned integer is 0, then the function returns 32, since all the bits are 0.

Syntax:

Math.clz32(number)

Parameters Used:
number :It is the value which is to be tested for CountLeadingZeros.

Return Value: It returns the number of leading zero bits in the 32-bit binary representation of the given number.

Examples:

Input : Math.clz32(5)
Output : 29
     
Input : Math.clz32(-5)
Output : 0

Input : Math.clz32(0));
Output : 32

When a positive number is passed as a parameter.
<script type="text/javascript">

document.write("Output : " + Math.clz32(5));

</script>
Output:
