RRCalc

RRCalc by Robert Rayment: (UPDATE Now stays on top) Not another calculator I hear you say. But I have this one on my Office bar and find it easier to see and use than the MS Standard calc. It has the usual numbers and arithmetic operators plus square root, square, reciprocal and pi; memory clear, store, add and recall along with a window showing what's in memory. All the buttons can be operated with the mouse or the keyboard. The zip file is 31KB.
