    Would have been 5 stars but for the stupid omission of a reciprocal key 1/x. Why?

    The ability to store and recall formula is great. This is a very good calculator but has a few drawbacks. The percentage key is not correctly implemented, the help file is in Spanish. It would be a 5 star if these little things were fixed and the formula and constants could be assigned to keys. UPDATE 26 May 2014: Help file now in English -[Hopefully this is the Beta version]
