Try this one:

var test = 2354.55;
var lastone = +test.toString().split('').pop();

console.log("lastone-->", lastone, "<--typeof", typeof lastone);

// with es6 tagged template and es6 spread
let getLastDigit = (str, num)=>{
  return num.toString();
};
let test2 = 2354.55;
let lastone2 = +[...getLastDigit`${test2}`].pop();

console.log("lastone2-->", lastone2, "<--typeof", typeof lastone2);

Updates with ES6/ES2015:

We can use tagged template in such case as numbers are not iterable. So, we need to convert the number to a string representation of it. Then just spread it and get the last number popped.
