Get data directly from the database

Hello I am retrieving the latitude and longitude from the database and I get this error:

syntax error, unexpected '<' 

The latitude and longtitude fields are varchar type and I am using this way the code:

The page has problem with this line:

'lat' => {{ $deviceinfo->address_latitude }},

If I put manually the coordinates then it works but from the database it doesn't work. Did someone have this problem?
