How can double be validated via jquery.validate?

Question

ASP.NET

Kind people, help!
I've been sitting on such a trifle for an hour now, it's already pleasant in my soul. Properties in the model:

[Range(Double.MinValue, Double.MaxValue)]
public double? Lng { get; set; }
[Range(Double.MinValue, Double.MaxValue)]
public double? Lat { get; set; }

Input value example: 42.56894, 5 decimal places. Not validated...
