This error message results when the compiler expected two types to be compatible (or similar), but they turned out to be different.
program Produce; procedure Proc(I: Integer); begin end; begin Proc( 22 / 7 ); (*Result of / operator is Real*) end.
Here a C++ programmer thought the division operator / would give him an integral result - not the case in Delphi.
program Solve; procedure Proc(I: Integer); begin end; begin Proc( 22 div 7 ); (*The div operator gives result type Integer*) end.
The solution in this case is to use the integral division operator div - in general, you have to look at your program very careful to decide how to resolve type incompatibilities.
