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 s  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  seems to need no more than this description does it  Perhaps there should be more elsewhere about doing arithmetic  EG There is no discussion of operator precedence or of rounding errors  Wogga
