Clear values only. What does 23 signify in .SpecialCells(xlCellTypeConstants, 23).ClearContents?

[OaklandJim]

I found a way to clear just values (no formulas, formats, etc.) from a specified range. I found this code: .SpecialCells(xlCellTypeConstants, 23).ClearContents. I am wondering what the 23 signifies? Excel intellisense says that the type is "Value"?

The 23 is pretty redundant, there are 4 options for the 2nd argument, which are

Enum name	Literal value
xlNumbers	1
xlTextValues	2
xlLogical	4
xlErrors	16

And you can add them together so 3 would be Numbers & Text, or 20 would be Logical & Errors, so 23 is all of them.
