JQuery :: Select All Inputs That Have A Value Containing A Minus Sign?

I am so close to finishing this project and I stumbled upon this block...

<div class="line first">
<input type="text" value="0,00" class="nbr first">
<input type="text" value="" class="date">
<input type="text" value="" class="date2">

[Code]...

I have here two inputs with class nbr. The initial values are set, and those values change programmatically over time. My list of inputs is a lot longer than this but I simplified. You can see the work in progress on [URL]. Just insert two random dates in page1 with the datepicker and the navigation will appear. At the end of a series of calculation I need to grab all inputs with positive numbers, and all inputs with negative numbers.I was thinking of selecting all fields with nbr class first, then use .filter() with a function

edit: nevermind, I found it.

$('input.nbr.first').filter( function(){
if($(this).val().indexOf( "-" ) !== -1) {return true} else {return false}
} )
