Example scripts to calculate the integral and zero points of functions using the AI code programmable calculator for Android.

import."mathlib"

// Math calculus examples

// Store the function in a variable 'fx1' .
// -e^(x-2)
{ 2 - e swap ^ -1 * } sto.fx1

// Integral
0    // start
2    // end
0,001    // precision
rcl.fx1  // f(x) as lambda
integral

// Zero point, uses the function inline.
-3    // start
{ sto.x rcl.x dup dup * * rcl.x dup * + rcl.x 4 * - 4 - }    // x^3+x^2-4x-4

AI code is a programmable calculator for Android.
AI code supports Forth-style definitions, variables, code import and lamda expressions. The latest update adds Vector/Matrix operations and statistics. Along with the color coded editor it is a new concept of using a programmable calculator.

I was in Maui for a few days at the Westin Maui Resort, Ka'anapali. The Garden next to the pools just nicely matched the "wwp921 Set" event of WorldWidePanorama.

AI code is a programmable calculator for Android.
It is also available within the StockRoom App to support financial calculations.

AI code supports Forth-style definitions, variables and lamda expressions. As an engineer, I have been using a HP calculator since University and this is how I imagine a modern programmable calculator. The app comes preloaded with lots of example code to try out.
Use :clearcode to remove all examples, and :defaultcode to restore all examples.
