Use long scale text labels (million, milliard, billion, billiard, etc.) when displaying alternate answers.

Add two pages of comparison operator toolbar to the long-press of 9 in scientific mode.

## Reverse Selected

 Author: vanLudwig Views: 121 Uploaded: 2018-06-01

Reverse the order of the selected item on the stack and all items higher (newer). So the selected item swaps places with the x register, next oldest item swaps with the y register, etc.

Sums the selected item and all items higher (newer) on the stack

## Sequence

 Author: vanLudwig Views: 118 Uploaded: 2018-05-30

Apply a function to all integers in a specified range, and push each result to the stack. So, it basically works exactly like $$\sum \left ( f, v, y, x \right )$$, except that it pushes each calculation rather than adding them and returning the sum.

Declare 26 standard letter variable registers

## Perfect Zero

 Author: vanLudwig Views: 133 Uploaded: 2018-05-26

Use the various rationalize snippets already posted to try to turn the results of MathZero into a perfect number. This can replace the standard MathZero in the toolbar if you so choose. Unfortunately doesn't play nice with the other solver functions the way the stock MathZero does.

## solve

 Author: vanLudwig Views: 121 Uploaded: 2018-05-26

Compute $$\text{solve}\left ( f_{1}= f_{2}, v, x \right )$$ where $$f_{1}$$ is in the t register, $$f_{2}$$ is in the z register, $$v$$ (the variable to solve for) is in the y register, and the initial guess for an answer is in the x register.

Replace the standard + button with a + button that will treat the selected line in your stack as the top of the stack. So, selected line is replaced with sum of selected line and the line above it. Works exactly like normal + if nothing is selected. It should be pretty obvious from this snippet how to replicate for −, ×, and ÷

## Rationalize Square Root

 Author: vanLudwig Views: 120 Uploaded: 2018-05-24

Turns a decimal value in the y-register into the closest $$\frac{a\sqrt{b}}{c}$$, where maximum value of c is in the x-register.

## Rationalize π

 Author: vanLudwig Views: 114 Uploaded: 2018-05-24

Turns a decimal value in the y-register into the closest $$\frac{a\cdot \pi}{b}$$, where maximum value of b is in the x-register.

## Hyperbolic Secant

 Author: vanLudwig Views: 140 Uploaded: 2018-05-23

Add $$\text{sech}$$ and $$\text{sech}^{-1}$$ as long-press on existing $$\cosh$$ and $$\cosh^{-1}$$ buttons. It should be pretty obvious from this snippet how to replicate for $$\text{csch}$$ and $$\text{coth}$$.
