Thanks appreciate the help. I've changed mind on doing this so going to leave as is but as a followup I did change all the 1's to 0 and made no difference.
I had already done this prior to post here and just tried again. Usually there is something else I'm missing anytime I make a change.
I really don't want just removal of decimal but want it rounded correctly off if removed. I see the big temperature was already zero and that's true, so I'm sure somewhere else it also needs changed.
//Temperature
var temp = convertTemp(realtime[2]);
set_ajax_obs("ajaxtemp", temp.toFixed(1) + uomTemp);
set_ajax_obs("ajaxtempNoU", temp.toFixed(1));
set_ajax_obs("gizmotemp", temp.toFixed(1) + uomTemp);
set_ajax_obs("ajaxbigtemp",temp.toFixed(0) + uomTemp);
