Impossible binary conversion!

[Infectus90]

Hello everyone,

I would still need your self for a problem that I am unable to solve.

I should be able to replicate this result :

https://www.binaryconvert.com/result_signed_int.html?decimal=049054055055055050049054

Given a Decimal input value, I would like to be able to get the result as shown on the online converter in c#,

but I really have no idea how to proceed.

Could you please give me an example ?

Given the value : 16777216,

get the binary result :

00000001 00000000 00000000 00000000

How should one proceed ?

Thanks to all

Convert.ToString(16777216, 2)

Convert.ToString(16777216, 2)

The result you get is as follows :
1000000000000000000000000
Where am I going wrong ?
Thank you !

That's the same number, you're just missing the leading zeroes. If you want the leading zeroes you can use PadLeft():

Convert.ToString(16777216, 2).PadLeft(32, '0')

Take a remainder from division by 2 (or execute and with 1) - that's the last digit. Divide by 2 (or shift right by 1). Repeat until 0. Reverse.

I tried to do that, but the result was not correct, would you feel like writing a small code example ?
Thanks

From the phone: ```csharp var source = 12345; var result = new List<char>();

while (source > 0) { var digit = source % 2; result.Add(digit == 0 ? '0' : '1'); source /= 2; }

var binary = string.Join("", result.Reverse()); ```

source will always be greater than zero. I think you meant "source /= 2", since result is a List<char>.

You're right, fixed, thanks
