javascript - Why does it keep adding a random 0? -

-

I was trying to create an MCT calculator in JavaScript, though during the construction of the mean, I received errors having had. This is my code: (Note that I am relatively new to javascript) 

  var min = prompt ("Enter the minimum value"); Var max = Prompt ("Enter Maximum Price"); If (min> max) {warnings ("Error: \ n \ n \ nminimum value '" + + + "maximum value greater than" "+ max +"'); } And {var a = (max - min); Warning ("variable one is" + max + "-" + minute + "=" + a); Var B = A / 2; Warning ("variable is b" + a + "/ 2 =" + b); Var c = min + b; Warning ("variable is" + minute + "+" + b + "=" + c); Warning ("range is + + + \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \" + + + \ n \ n Median + "+ + +" + \ n \ n max "max +" \ n \ n Max is "max");
< P> If you type 10 for the minimum value and 10 for the maximum value, then it will tell you that 5 is greater than 10 but this is not .. And if you type 10 for the minimum value and maximum value For 15, the average should be 102.5 instead of 12.5. I do not get it at all, please help :)

Use the numbers Try it, try not to string: 

  var min = parseInt (prompt ("enter minimum value"), 10); var max = parseInt (prompt ("Enter maximum value") ,

Or, if you want to allow floats: ); Var max = parseFloat (Prompt "Enter Maximum Price");

This is because stringics are compared to Lichxography, because instead of the value of the number Use Nkyatmk character code.

Is there something that I'm doing wrong?
