Looking for better scientific calculator app (OS-X)

[eric_n_dfw]

I'm looking for a good, simple scientific calculator app for my 8th grade son to use on his MacBook Air. The Apple one works fine but in scientific mode it takes up too much horizontal screen space. Looking for suggestions of another one out there that has a more vertical layout.

Basic needs are keyboard input, memory, square/cube root and exponents.

Perhaps PCalc ($9.99) .. It has different horizontal/vertical layouts to fit different needs. And a nice notification widget that might help on space. And keyboard support.

I love PCalc, have it installed on OS X and iOS. I don't use many of the scientific functions, but they are there. Also RPN, for those weirdos who like that.

CalcMadeEasy Free (on the store) works well for me.
It's got all the things you expect in a non-programmable scientific calculator.

Big advantage over Apple's "Scientific" calc"
CalcMadeEasy gives 7/11e23 = 6.3636e-24
Apple's version gives 7/11e23 = 0 NOT VERY SCIENTIFIC! It seems to use fixed point arithmetic even in scientific mode. That can cause all sorts of trouble if you're not aware of the issue.
