What users said (iPad version):

"This is by far the best RPN calculator available for the iPad!"

"Great app that I would recommend to anyone who grew up with an HP-45!"

"Calculator works great just like my original HP-45. Worth the price and brings back memories of using the slide rule before getting my HP-45."

"This is one of the most accurate but also nicest looking emulators I have come across for the HP-45, or any vintage HP calculator for that matter."

"With the Super-45 mode functions that were added by the developer, this is an extremely powerful calculator. Very elegant design."

What's new

• In SCI and ENG notation, command RND now rounds the mantissa only, not the entire number
