I am looking to calculate a square root in a measure I'm writing, but the math.sqrt() method does not work. Is there a way to include Ruby's Math module when writing measures or is there another way to use the higher level math functions?

@Alec I re-tagged your post to include the existing openstudio-measure tag, rather than openstudio-measures

I think the issue may be that the Math module needs to be capitalized, try

Math.sqrt(4)

I'm guessing you would do something like...

require math

...at the top of your measure.

It's also worth a search of your local BCL folder for "math" to see how it's used elsewhere.
