Is the closing fraction indicator in Nemeth the same as the number sign?

Explanation:
In Nemeth braille, some markers are reused for different purposes to keep the system compact. The closing fraction indicator uses the same braille cell pattern as the number sign, so they are effectively the same symbol. The reason is that both markers serve boundary-related roles in math notation: the number sign flags that numerals will follow, and the closing fraction indicator signals the end of a fraction within a mathematical expression. Readers rely on the surrounding mathematical structure to interpret which role is intended, but the actual dot pattern is identical.
