I think this must be my first contribution to Wikipedia anywhere So be kind to me I have to own up to being a newby at JavaScript though I have been in computing since the 1960s I would be grateful for any suggestions or comments about my attempt to insert a description of the Math object The place where this appears 5 4 seems to need no more than this description does it Perhaps there should be more elsewhere about doing arithmetic E G There is no discussion of operator precedence or of rounding errors Wogga62
