Major credit needs to go to Korax over on the WoW curse Addon section. I used Korax's code as my base and inspiration. You can visit Korax's download page here:

Description

This is an in-game gui Calculator with most of the basic functions working (adding, subtracting, multiplication, and division. You can also string operations together.

Installation

UnZip the guiCalc v0.4.zip file to your Runes of Magic installation directory and re-login to the game. When you re-login into the game you should receive a chat message stating that guiCalc has been added.
When you UnZip it you should end up with a folder similar to this:

When in game simply type "/guiCalc" or "/gc" in the chat window. The Calculator frame will open.

Memory Buttons:

MS = Memory Save - This will save the currently displayed number to memory.
MR = Memory Recall - This will recall the number saved in memory and display it.
