## About The Pull Request The binary conversion circuit component is totally busted at the moment, so I redid the logic and now it actually outputs a series of bits to represent whatever number you feed it. Additionally, it supports representing a negative number by setting the leftmost bit of your bit array to 1. ## Why It's Good For The Game Fixes a broken circuit component and makes it able to represent negative numbers ## Changelog 🆑 Bisar fix: The binary conversion circuit component should work again. code: The component also now supports representing negative numbers. /🆑 --------- Co-authored-by: SyncIt21 <110812394+SyncIt21@users.noreply.github.com>
