√-1

√-1 is a stack-based language created by User:Broxol. It is designed to only allow stacking of imaginary numbers.

This language was made from the inspiration page, so I’m not going to really explain it, but I do have some examples.

Unfortunately, I did not add any form of inputting. I’ll fix that in a future version.

EXAMPLES

Hello, World program:

Hello,|World! print

1 + 1 program:

1j 1j 1j 1j * * * dup + print
