Delphi Compiler Error
E2186 Published Real property ‘%s’ must be Single, Real, Double or Extended
Reason for the Error & Solution
You have attempted to publish a property of type Real, which is not allowed. Published floating point properties must be Single, Double, or Extended.
program Produce;
type
Base = class
R : Real48;
published
property RVal : Real read R write R;
end;
end.
The published Real48 property in the program above must be either removed, moved to an unpublished section or changed into an acceptable type.
program Produce;
type
Base = class
R : Single;
published
property RVal : Single read R write R;
end;
end.
This solution changed the property into a real type that will actually produce run-time type information.
