Math scholars are acutely aware what $3.14 gets them on Wednesday.
March 14 is Pi Day, an annual celebration of the mathematical constant π (pi), which is the ratio of a circle's circumference to its diameter. The trillion digit ratio is rounded to 3.14.
For the rest of us, it's simply a day of deals on pizza, pastry and pot pies.
