===Alternative forms===
Early forms (e.g. in Euler's texts) may approach a 'lazy S', [[∾]].
It has also been attributed to {{w|John Wallis}} and conjectured to originate from {{l|mul|ↀ}}, since 1,000 was hyperbolically used to represent very large numbers.

# A symbol representing [[infinity]].
#: {{lang|mul|∞ + ∞ {{=}} ∞|sc=Zmth}}
