Conversion decimal to binary

[Chris12345]

Hello,
I’m looking for a solution to convert decimal values into binary in knime.

I found this thread:

How to convert decimal to binary?

Hello any idea how to convert a decimal value to binary? example: in Excel DEC2BIN(156) = 10011100 How to do it with KNIME? Thank you

, which is something like half way for me, as i would like to convert doubles into binary, which is not working with the Java “Integer” input.

Is there somebody how could help me please, so solve this issue?

Thanks a lot
Chris

Hi @Chris12345

This was nice challenge I posted my workflow on the hub.
Because it loops every record, it is not that fast… But I think it works. I checked the resutls on this website https://www.rapidtables.com/convert/number/decimal-to-binary.html . But better see for yourself as well.

@Chris12345 you can try and employ a Python node to convert doubles into binaries (following “IEEE 754 binary representation of floating-point numbers”) - I have employed ChatGPT which took some loops and changes but now the results seem to be good.
