suffix 

Values for the suffix element include the accidental values sharp, flat, natural, double-sharp, flat-flat, and sharp-sharp. Suffixes include both symbols that come after the figure number and those that overstrike the figure number. The suffix value slash is used for slashed numbers indicating chromatic alteration. The orientation and display of the slash usually depends on the figure number. The suffix element may contain additional values for symbols specific to particular figured bass styles.
