Version 1.1.0

A new version is coming shortly to the App Store. Here are some of the changes for this upcoming version:

  • Added a calculator tab for numerical calculations
  • Updated the keyboard layout. The same keyboard is used for editing equations and doing calculations.
  • Added the ceil() and floor() functions
  • Made the arrow and delete buttons smarter. Function and variable names are completely deleted when the backspace button is pressed. The previous version used to delete them one character at a time.
  • Added the ability to turn equations on/off without having to clear them
  • Fixed the inverse trigonometric and hyperbolic functions
  • Added a new splash screen

The biggest change is a new calculator tab for numerical calculations. This was the #1 most requested feature. Many people that downloaded my "Graphing Calculator" asked where the calculator was. At first, I didn't see why this was needed since Apple included a scientific calculator already, but I changed my mind. Unlike Apple's calculator, this lets you type in the whole expression, and it will let you go back to fix mistakes. Also, you are able to scroll through a history of recent calculations just like on TI graphing calculators. In addition, it allows you to evaluate the equations you are currently graphing at any X value. Here's a screen shot of what this new tab looks like:
