Hi,

I want to know how to convert a decimal integer into its binary form??

I came across a code which used BIT OPERATORS; I could not understand it.

pLEASE HELP ME WITH THIS.

Note: This is not my ASSIGNMENT PROBLEM. I know one way of converting decimal into binary and the code is as below..

binary = 0

while decimal != 0:

bit = decimal % 2

binary = bit + (10 * binary)

decimal = decimal / 2

I want to know the other way using BIT operator and thats why I have posted this query.

Thanks in advance.

Regards,

Asrar

To HIM you shall return.

Take a look at this Python code snippet at:

http://www.daniweb.com/code/snippet360.html

It uses a bitwise shift right operator to get the binary representation of an integer.

Editor's note:

I think we lost the reference when snippets were folded into the regular forum. Looks like Ene refers to ...

```
def denary2binary(n):
'''convert denary integer n to binary string bStr'''
bStr = ''
if n < 0: raise ValueError, "must be a positive integer"
if n == 0: return '0'
while n > 0:
bStr = str(n % 2) + bStr
n = n >> 1
return bStr
# test
print(denary2binary(255)) # 11111111
print(denary2binary(128)) # 10000000
print(denary2binary(127)) # 1111111
```
