Seems you are right: Delphi Tokyo 10.2 X = -1 VarIsFloat : FALSE VarIsNumeric: TRUE VarIsOrdinal: TRUE After Abs() X = 1 VarIsFloat : TRUE VarIsNumeric: TRUE VarIsOrdinal: FALSE So, would it be possible to have an overloaded Abs(V: Variant): Variant; function in the variants unit? To be clear. Personally I don't need it (at least not ATM), I'm just curious. Thanks for explaining.
