Hi there I'm trying to convert Decimal to Hex with raw code as a challenge someone gave me but im struggling to figure out why the the payload that's shown in the debug node is "undefined". Thank you in advance for the help Kind Regards Apple [{"id":"d3a188d4.8d7a5","type":"tab","label":"Flow 1…

Upfront info to keep in mind / refer back to... & is a Bitwise AND & 0xF means AND the value with 0xf (or decimal 15 or binary 0000 1111) >> is a Sign-propagating right shift >> 4 means shift the bits in a number 4 to right - effectively dropping the right most digit & moving other digits in the n…

This code ↑ works. What is your issue? Could you post your code that is not working (with a suitable inject to simulate the problem)

wait what? how does it work for you its not working at all for me, my payload returns as undefined and the only node.warn that works is the one outside of the while statement. im confused as to how its working for you?

The flow you posted above in your last message... [image] Apple: [{"id":"d3a188d4.8d7a5","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"62f0c6d6.6621a8","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"b4480307.eea488","type":"ui_tab","name":"Text","icon":"dash…

else if (res<9>16) That isn't valid javascript. Well actually it is valid, but it tests res<9 which gives true or false and then says is that >16, which isn't very useful. I assume that what you mean is else if (res > 9 && res < 16) though quite how you thought your original would…

Yes i need to do the conversion myself without any calls of toString
