Answer 1

toString() converts number to string, and charAt() gives you the character at a particular position.

var str = 3232.43;
lastnum = str.toString().charAt( str.length - 1 );
alert( lastnum );

Answer 2

Here is another one using .slice():

var test = 2354.55;
var lastDigit = test.toString().slice(-1);
//OR
//var lastDigit = (test + '').slice(-1);

alert(lastDigit);
