Why does Firebug say toFixed is not a function

Question

I am using jQuery 1 7 2 and jQuery UI 1 9 1  I am using the code below within a slider   http   jqueryui com slider    I have a function that should test two values and depending on the difference between the two values reformat them  to the appropriate decimal place   If the difference is greater than 10  I will parse out the integer  If the difference is greater than 5  it should keep one decimal  Everything else  I will keep two decimals     When I enter two values that have a difference that is ten or less  I use the toFixed   function   And  in Firebug  I see an error   TypeError  Low toFixed is not a function Low   Low toFixed 2     Is there something simple that I am doing wrong     Here is my code   var Low    SliderValFrom val    High    SliderValTo val        THE NUMBER IS VALID if  isNaN Low     false  amp  amp  isNaN High     false        Diff   High - Low  if  Diff  gt  10          Low   parseInt Low       High   parseInt High         else if  Diff  gt  5           Low   Low toFixed 1          High   High toFixed 1     else          Low   Low toFixed 2      High   High toFixed 2

Low is a string   toFixed   only works with a number  A simple way to overcome such problem is to use type coercion  Low    Low 1  toFixed       The multiplication by 1 forces to code to convert the string to number and doesn t change the value

toFixed isn t a method of non-numeric variable types  In other words  Low and High can t be fixed because when you get the value of something in Javascript  it automatically is set to a string type  Using parseFloat    or parseInt   with a radix  if it s an integer  will allow you to convert different variable types to numbers which will enable the toFixed   function to work   var Low    parseFloat  SliderValFrom val         High   parseFloat  SliderValTo val
