Superscript is difficult to realize in computer text files, except that it is difficult to save in a database with special fonts. The representation of superscript is beyond the scope of ASCII, but for numerical superscript, it can be achieved by copying and pasting.
In mathematics
In mathematics, some symbols are marked with superscripts. Have ∑, ∏, ∨, ∩, ∧, ∫? 、∮。 Among them, the superscript ∨, ∩ and ∧ all indicate the upper bound, ∏, ∫,? The superscript of ∮ and ∮ is gradually matched from the superscript or the auxiliary information of the mark is written. Numbers are also marked with superscript, which represents several squares and can be written as log superscript (x).
