Why does Firebug say toFixed() is not a function?
javascript
Solution
`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());
Problem
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 && isNaN(High) == false) { Diff = High - Low; if (Diff > 10) { Low = parseInt(Low); High = parseInt(High); } else if (Diff > 5) { Low = Low.toFixed(1); High = High.toFixed(1); } else { Low = Low.toFixed(2); High = High.toFixed(2); } } ```
