      This ticket is related to the user's question in CSHARP-2908.

      Currently, this projection logic:

      var resultProject = collection
.Aggregate()
.Project(
	el => new { DividedPopulation = ((el.Population / 23))            
})
.ToList();

      will fail with FormatException, because we're trying to convert a double field from server response to int. We need to consider a convert top-level json node to the generated request, for example, to something like this (added `$toInt`):

      { $toInt : { $divide : [ ... ] } }

      It's possible that this ticket will be implemented in the scope of LINQ redesign ticket CSHARP-2608
