[fpc-devel] Abs(Variant) unexpected result

[Bart]

Hi,

See: http://forum.lazarus.freepascal.org/index.php/topic,40223.msg277657/

This seems rather unexpected.
Is it a bug?

program v;

{$ifdef windows}
{$apptype console}
{$endif}

uses
  variants;

var
  X: Variant;
  B: Boolean;

begin
  X := -1.5;
  writeln('X = ',X);
  B := VarIsFloat(X);
  writeln('VarIsFloat  : ',B);
  B := VarIsNumeric(X);
  writeln('VarIsNumeric: ',B);
  B := VarIsOrdinal(X);
  writeln('VarIsOrdinal: ',B);

  X := Abs(X);
  writeln('After Abs()');
  writeln('X = ',X);
  B := VarIsFloat(X);
  writeln('VarIsFloat  : ',B);
  B := VarIsNumeric(X);
  writeln('VarIsNumeric: ',B);
  B := VarIsOrdinal(X);
  writeln('VarIsOrdinal: ',B);
end.

Outputs:
C:\Users\Bart\LazarusProjecten\bugs\Console\variants>v
X = -1,5
VarIsFloat  : TRUE
VarIsNumeric: TRUE
VarIsOrdinal: FALSE
After Abs()
X = 2
VarIsFloat  : FALSE
VarIsNumeric: TRUE
VarIsOrdinal: TRUE
