Hi *,
seems, that overloading of Inc, Dec internal compiler procedures is not
allowed.
Is it by intention or can it be fixed (adding overload keyword to system
function definitions?).
I would like to add support for:
procedure Inc(var a: integer; b: single); overload; inline;
begin
a := a + Round(b);
end;
procedure Inc(var a: single; b: single); overload; inline;
begin
a := a + b;
end;
procedure Dec(var a: integer; b: single); overload; inline;
begin
a := a - Round(b);
end;
procedure Dec(var a: single; b: single); overload; inline;
begin
a := a - b;
end;
But nor this approach nor operator overloading is allowed.
(Error message: Wrong number of parameters specified for call to "Inc"
is emited , when simple Inc(a); is used
I can avoid this error by prefixing System.Inc(), but it will require
change on many places in code)
I need use addition or subtraction on operands, which left of them can
be either "integer" or "single" type (specialized generic type)
Example:
var x,y: TAnyNumericType; x1,y1: single; i: integer;
Inc(x, x1); // x,y can be either integer or single
Inc(y, y1);
Inc(i); // Error: Wrong number of parameters specified for call to "Inc"
TIA
-Laco.
