Group Functions

Anonymous — Sun, 31 Oct 2010 20:44:42 -0000

Add a submenu to Edit > Group Equation.

This will take the whole display equation and group it so following functions can be applied to the whole equation. For example:

4+5*3 is in the display. Press Group Functions and that changes to (4+5*3) so that way all following operations are applied to the whole function. If display=0 then do nothing.

The calculator currently has to methods of inputting equations. The documentation should mention this but currently does not.

Change button functions

Replace sqrt with %
Replace x^2 with <<
Replace x^3 with >>

Set up the backspace function so that when << is deleted it deletes both << and not just a single <. Same for >>.

Change button Layout

Make the backspace span 3 cols and AC span 1 col.

Make the widths of the backspace and CE button wider so they line with the edges of the buttons below them.

Create a math library

Sam Gleske — Wed, 07 Oct 2009 04:37:40 -0000

I wish to turn the Scientific Calculators math engine (which takes a string and then calculates it) and turn it into a library. That way it is easily portable to other web applications and interfaces.

It's main interfacing function will be compute("string") and it will return an int or false (false if there are calculation errors).

The Scientific Calculator will serve as a real world example of the math library.

ln, log, and exp functions

Have ln(#), log(#), and exp(#) (or e^#) calculate from within the calculation similar to how sin, cos, and tan are setup.

For example in the calculation display:
ln(1)+3

(which is = 0 + 3 = 3)
