Error message for wrong type metafield can be confusing at time

Description

When a value set to a metafield which does not match the type of the metafield itself, there will be this error message:

System.ArgumentException: value is a System.Double but should be a System.Int32
Parameter name: value
at Mediachase.MetaDataPlus.Configurator.MetaDataTypes.GetDatabaseValueInteger(Object value)

This is confusing and is not helpful to resolve the problem. Suggested error message is:

"Value of <metafieldname> is 4.5, of type double, but should be an int"
