Simply the best free scientific calc in app store

I use it all the time for hexadecimal calculations and conversions from hex to decimal (took a while to notice the configuration setting to change it from the default 16 to my needed 32 bits though). The C key clears the corrently entered number only so I can fix a typo without re-doing the whole calculation, and the option to use engineering notation makes working with large numbers much easier. My thanks to the author for putting so much functionality into a free app!
