Imaginary numbers aren't handled correctly

[programmerlexi]

The expression e ^ (i * pi) + 2 evaluates to one.
Mathjs provides a round off error alongside of the result (i don't know why).
The bot evaluates the expression to 0.

Even things as simple as i^4, which evaluates to 1 for both my brain and mathjs, don't evaluate correctly for the bot.

Upon further investigation it seems imaginary numbers aren't handled all too well.
This seems to be an issue with this bot, not with mathjs.
Mathjs correctly calculates sqrt(-4)^4 to be 4, the bot seems to think it's 3.

i'll take a look at this!
