Welcome to the complex number calculator!

It's slowly getting pretty and it should be functional. There's just a couple of rounding errors that should be sorted out at some point. Watch this space and it will improve and may even have an explaination of how it works!

History:

Use j or i for square root of minus one?

"j" "i"

Ctrl + Numpad 1 = j

Ctrl + Numpad 0 = E (exponent of 10)

Ctrl + Numpad 4 = < (Angle)

Ctrl + Numpad 5 = rad

Ctrl + Numpad 6 = deg
