The <sup> tag is used to define a superscripted text. Superscript text appears half a character above the baseline. The tag can be used in combination with other tags to change the text style. For example, if you enter the following expression:
Test <sup>Test</sup> Test
then after calculation the result appearing in the report will be:
Test Test Test
If a tag is not closed then the formatting is applied to from the opening tag to the end of the text expression.
