"Does not constrain values to within the range, because out-of-range values are sometimes intended and useful. The constrain() function may be used either before or after this function, if limits to the ranges are desired. "

Suggested version
"Does not constrain values to within the range, because out-of-range values are sometimes intended and useful.  For example: if the incoming value is below the fromLow value, the outgoing value will be negative in proportion to the given toLow - toHigh range. The constrain() function may be used either before or after this function, if limits to the ranges are desired. "

I didn't know what exactly the map function would do with out-of range numbers.  With a short explanation like this I would have understood immediately.  I think it would be quite helpful to other learners (ok, noobs) like myself.

P.S. the reference page says to post suggestions in the forum and gives a link.  Is this the correct forum?
