# Meaning of symbol $\looparrowright$ in math

• It seems that it is being used as an "em dash". For more information, see <thepunctuationguide.com/em-dash.html>. I want to add that it is certainly not standard, and personally is somewhat distracting. – Alberto Takase Mar 13 at 18:24
• @AlbertoTakase I'm not sure, it still confuses me. – Likely Mar 14 at 7:44
