Zèv li yo 
 Matematisyen sa a travay anlè Pi (  ) depi li te jèn timoun. Li bay fòmil sa a :

ki pèmèt jodi jou kalkile anpil desimal nan nonm .

Li pa te genyen edikasyon matematik men li te konnen matematik nan potomitan li. Se pousa tout fòmil li te twouve yo pa te genyen demonstrasyon dèyè yo. Demonstrasyon fòmil pou  nou bay an ke Ramanujan te dekouvri nan lane 1910 te demontre nan lane 1985 pa frè matematisyen sa yo : Jonathan epi Peter Borwein.

 Li travay tou anlè sa yo rele fraksyon kontini :
