There really isn't a question here. Can you explain what it is you would like to achieve? — Kolban, Nov 10 '14 at 05:03

split() Method is a member of string. Since outputCMVal is a number, you need to call .toString() method before .split('.')

arrDecimal = outputCMVal.toString().split('.');

jsFiddle demo

Concatenate it to String before splitting by Character .

var cm = 14*2.55;
var outputCMVal = Math.round(cm*10)/10;
alert(outputCMVal);                              // 35.7

var arrDecimal = (outputCMVal+"").split('.');    
alert(arrDecimal[1]);                            // 7

also assign your var
