Jquery & C# deciaml and parseflot values are different

Question

I have a backend code and i try to do the same in frontend using jquery.But result's are different.(correct value is C# code retuns value.)

C# Code

var geoConvr = (decimal)141.5 / (decimal(1) + (decimal)131.5); // Result -> 1.0679245283018867924528301887M

Jquery Code

var geoConvr = parseFloat(141.5) / (parseFloat(1) + parseFloat(131.5)); // Result -> 0.12505523641184269

So i need to get a same value that C# returns from the Jquery code.
