I would like there to be a function that returns the background color of a cell.  If the color is best described as an RGB set (0-255, or whatever), then there can be three arguments (location & RGB color).ie: bgcolor(row,column,RGBcolor) -returns the component (0-255) of the cell(row,column)so =color(25,16,RED) would return the RED component of cell(25,16).  If the argument RED isn't a defined constant, simply establish a standard code (RED=1, GREEN=2, BLUE=3)Thanks,Will

Calc Add-ins

Function to return roots of quadratic equation

Formerly bug 122171

Quadratic equation ax^2+bx+c=0

Proposed added function:

  • quadratic(a,b,c,1) will return (-b+sqrt(b^2-4ac))/(2a)

  • error if complex root

Numerical integration - Simpson's rules

Formerly bug 122202

Given: equally spaced x values, x0 till xn and respective function values in two columns
