I've put the functions I use most often as long presses on number and operator keys and I've put labels on the keys to show this. The lower (and smaller) function label on a key is invoked by a long press.

Variant of stock layout with many extra functions available though long-press. Look for the shaded upper-right corner of toolbar buttons to indicate they have a long-press function. Also, long-press 7 for scientific constants, 8 for unit conversions, 4 for calculus/solver functions, and 5 for TVM financial functions.

HP 32SII

Pretty decent replica of an HP32SII. It obviously isn't programmable, and there's a few other buttons I had to change or repurpose, but it gives you a good idea of what's possible through layouts.

Layout that includes the "where" function. This layout includes a row with six buttons, but to me it looks fine! I've added borders to the buttons and I've changed the "Change sign" key label from "(-)" to a more traditional "CHS".

Here's my first attempt. It adds an extra row of keys above the numbers to give access to some of the new functions. The added keys are: x - a variable for use in the functions below; zero - finds the zero of a function of x; integ - integrates a function of x between specified limits; deriv - finds the numerical derivative of a function of x at a particular value of x; sigma - sums a function of x over a specified range.

Extremely primitive layout based on the Casio SL-240LB. This is a good place to start if you want to write a layout from scratch, especially if you are trying to mimic a physical calculator.
