New Acron RPN Calculator for Android

[ijabbott]

I downloaded the free version and was impressed by the novel stack display and clean interface, so I splashed out £0.79 on the paid version.

I have a few suggestions for additional that should be simple to implement:

• csc⁻¹(x), sec⁻¹(x), and cot⁻¹(x)
• degree forms of csc(x), sec(x), and cot(x), and their inverse functions, if implemented (but this would push the sin, cos and tan button menus to three pages each)
• there is space on the ? button soft menu for another constant, possibly the golden ratio, ?
• the gamma function ?(x), or failing that, implement x! for real numbers as ?(x+1)
  

In addition, rectangular to polar and polar to rectangular conversions would be nice (in both radian and degree forms), but as those functions would replace two values on the stack with two new functions, it would wreck your nice, augmented stack display something horrid! An alternative would be to implement them as part of complex number support, but you might not want to go down that road just yet!

Thanks for producing a nice calculator app!
