How to generate either absolute value and non absolute random numbers in JS

Question

With this code:
function (min,max) {document.getElementById("num").innerHTML=Math.floor(Math.random*(max-min)+min;}
With the HTML file already with "num" id it generate random positive number when the assigned button is clicked. when the (max-min) is replaced with(min-max) it will generate random negative number. I am asking how to make it show either negative or positive with one code without writing for negative and positive differently.

Answer 1

Ok a little mistake in the code {....(Math.random()*......}
