Document Summary
Properties: attributes of objects (value, text, count, column, row, address, etc) Methods: actions to be taken on objects (select a cell or ranges, clear) Selection. cells(3,3) (row 3 column 3 of current selection) Can use excels functions like using pi by application. worksheetfunction. pi() Ask user for a number and display the square root. Start (circle) input x (parallelogram) square root of x (square) output y (parallelogram) end (circle) Double: used for numbers with decimal fractions and possibly exponents where high precision or extended range are required. Range: from about 10^308 down to 10^-309, both + and . String: used to store text (just a word) Boolean (also called logical): used for t/f information.
