When i googled everyone using this method STGeomFromText
LocationGeography = geography::STGeomFromText('POINT(@Latitude @Longitude)', 4326)
What is the problem with this statement

The variables you have are already of datatype float, making the conversion to string superfluous.

As the error says your passing in floats and trying to build a string, change them in the declaration to varchar or convert in the query.

UPDATE [MarvelTour_DEV].[dbo].[LocationCopy]
SET
LocationGeography = geography::STGeomFromText('POINT('+CAST(@Longitude AS Varchar)+' '+CAST(@Latitude AS Varchar)+')', 4326)
WHERE LocationID = @ID

So these methods only take Varchar datat type only after converting to varchar it is working
Thanks
