spec - an html/javascript calculator todo -
think of some todo items make the button have
the effect do the calculation show the
result - think of how you want the calculator to
look -check the result is correct -write some
CSS to change the outlook -align the result to
the correct position - do we want
modes? -define modes - think about how to
implement that -organize the buttons and text
area to look like a calculator (probably in a
table) - improve the positioning of the

spec - an html/javascript calculator todo -
need to decide on full set of operations (right
now only basic ops) - need to decide reverse
polish notation vs. standard notation - make the
buttons have some effect - do the calculation -
show the result - decide on look feel
(currently minimal) - not sure what the below
items are -check the result is correct
-write some CSS to change the outlook -align
the result to the correct position - do we want
modes? no -organize the buttons and text area to
look like a calculator (probably in a table) -
improve the positioning of the buttons done -
made some buttons and a text area
// TODO state of
calculator // e.g. store previous number when
operation is clicked // TODO functions to
implement calculator function handle(something)
alert(something) // TODO handle the
click area rows"1" col"20"

Michael spec - an html/javascript
calculator todo - need to decide on full set of
operations (right now only basic ops) - need to
decide reverse polish notation vs. standard
notation - make the buttons have some effect - do
the calculation - show the result - decide on
look feel (currently minimal) - pow function to
deal with negative powers - not sure what the
below items are -check the result is correct
-write some CSS to change the outlook -align
the result to the correct position - do we want
modes? no But lots of calculators have temporary
modes, e.g. a 2nd or 3rd function button that
modulates the characters. Maybe we should follow
the typical approach? -organize the buttons and
text area to look like a calculator (probably in
a table) - improve the positioning of the
buttons done - made some buttons and a text
area
// TODO state of
calculator // e.g. store previous number when
operation is clicked // TODO functions to
implement calculator function handle(something)
alert(something) // TODO handle the
click function add(x, y) return x
y function subtract(x, y) return x -
y function pow(x, powNum) if (powNum
0) return 1 else return x (pow(x,
powNum-1)) idcalculator col"20" onclick"handle(1)"1
