Well explained! Thanks for sharing your knowledge.

@Discordanian Well explained! Thanks for sharing your knowledge. @Rashmistrz Well done an welcome back. Regards

I used mask to get only sign bit and reversed it with bitwise negation
(because I didn't want to use logic one) to get true when it needs reversing.

Negation was done using inline assembly
by taking 'num' to register, negation
and putting it back to it's place.

Literally you summoned me back.
I wasn't using this site for more than year and
I spotted your question in recieved e-mails.

Very nice! Can you explain it? Regreets

Love solutions like this. Well done, Rashmistrz

There... no bitwise ;)

lul, cant figure it out ?

Bitwise feels like cheating but I'm still technically not using "&&" and "||"!

Added tests and made the classes static/public and now runs

this is c#, get rekt btw
