I can't get the sqrt or pow macros to work.

For example

`(set: $num to (sqrt: 25) )`

Just stores a 0 in $num. No matter what I give it as input, sqrt seems to evaluate to zero.

Likewise, even though the documentation says pow should be used like (pow: 5, 2), it complains that pow only takes 1 argument. Giving it 1 argument evaluates to zero.

I've tried testing in a few different browsers and with the online and downloadable version of Twine.

I'm not sure what I am doing wrong with these functions. Any help is appreciated.
