Try using this approach http://geekswithblogs.net/danemorgridge/archive/2010/12/20/ef4-code-first-control-unicode-and-decimal-precision-scale-with.aspx

or

The simplier one:

public class MyContext : DbContext
{
    public DbSet<Metrics> Metrics { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Metrics>().Property(x => x.PPM).HasPrecision(4, 3);
    }
}

Good luck!
