In Delphi, what is the method to obtain a numeric variant property?

edit

To obtain a numeric variant property in Delphi, use the "AsExtended" method. This method converts the variant property to an extended data type, which is a numeric data type that can handle very large or very small floating point numbers. For example:

var myVariant: Variant; myNumber: Extended; begin myVariant := 123.45; myNumber := myVariant.AsExtended; ShowMessage(FloatToStr(myNumber)); // Displays "123.45" end;
