Decimal Trimmed after 2 digits added Zeros while store to sql server

I trying to store the Latitude and Longitude to my Database.
I have My column type in DB as

[Latitude]              NUMERIC (12, 8)                NULL,
[Longitude]             NUMERIC (12, 8)                NULL,

In C# Model my Properties are

    [Column(TypeName = "numeric")]
    [Range(-9999.99999999, 9999.99999999)]
    public decimal? Latitude { get; set; }


    [Column(TypeName = "numeric")]
    [Range(-9999.99999999, 9999.99999999)]
    public decimal? Longitude { get; set; }

I want to store this Latitude and Longitude value to my Database table

What am doing wrong here please help

decimal lats = decimal.Parse("56.12345678");
        decimal longs = decimal.Parse("10.18732210");

        context.test.Add(new test
        {
            Latitude = lats,
            Longitude = longs
        });
        context.SaveChanges();

it stores Like in DB
Like This

Latitude: 56.12000000  and Longitude : 10.18000000

I want the Same Value to be stored in DB
"56.12345678" and "10.18732210";

>Solution :

You probably need to specify it also in your OnModelCreating like this:

modelBuilder.Entity<Test>().Property(a => a.Latitude).HasPrecision(18, 9);
modelBuilder.Entity<Test>().Property(a => a.Longitude).HasPrecision(18, 9);

Just in case you need more advanced features and you are using EF Core take a look at:
