Showing the binary representation of an integer.

I see a lot of people asking about getting the binary (string) representation of a number in various languages. Changing the base for a number is not that tricky, and getting the binary representation of the a number is really easy.

All this uses is a simple bit shift (">>" right shift), and the the AND ("&") bit operator. These operators are pretty common. Here is a simple Python function to convert the number.

>>> def tobinary(n,size=32):
...     return ''.join([str((n >> i) & 1) for i in range(size -1, -1, -1)])
...
>>> tobinary(0xF, 8)
'00001111'
>>> tobinary(5, 8)
'00000101'
>>> tobinary(4, 8)
'00000100'
>>>

				

Yup, that's all there is to it.

Very Important

I was going to upgrade this server, but then I realized I don't want to. It's a PIII 450mhz machine, with 256MB of memory. There is an 8GB Western Digital drive as the primary drive, and then a 40GB Western Digital driver for extra storage.

I bought it from Percy's (when they custom built computers), a while back. It rocks the house and rules the internet.

Thanks for reading my blog.

Scheck

I posted the source to my server monitoring program. It's very simple, but it worked for me at 2 of my past jobs. It's free and released under the LGPL.

NTimer

NTimerLib, NTimerGUI, NTimerCL
I posted my free time tracking tool, called NTimer ( uses NTimerLib ), and all of the source code. It's written entirely in C# and will build and run using the .NET 2.0 framework and Mono. You can find it right here. The current version is 0.1 and is released under the LGPL.
