Type Mismatch with constants

[A-man]

I have the code

var 
 x: integer;

Const
 W = 512;

begin
 x := W/16;
 writeln(x);
end;

 

the line with x := W/16 throws a type mismatch. I think it has to do with the division, but I'm pretty sure it didnt used to do that before. I also tried using x := int(W/16); and that didn't work either. There is more to my code, this is just the essentials of the scenario. I should note that if I replace the W/16 with 32, the code executes perfectly.

It should throw an error regardless of the number you use. The integer division symbol is div. SCAR is very strict about the syntax rules. Takes a bit of getting used to.

 

[sCAR] x := W div 16;[/sCAR]

In math integers are defined as being natural numbers, 0, and negative numbers. Not fractions! I'm no math genius but that is what an integer is (google it).

 

So thus you can't divide the Integer 2 / 3, because that would end up being a fraction. But if you had 2 as a type called Extended which can be a fraction. Then you could do it. DIV is used to divide the number evenly, and I think it rounds either up or down.

var

x: Extended;

 

Const

W = 512.0;

 

begin

x := W / 16;

writeln(x);

end.

Ahh thanks, that makes sense
