PI DAY
Hey! We have another interesting date. It's PI day! Today is
3/14/15
PI day (March 14, 3/14) happens once a year, but this special PI day (3/14/15) happens only once a century!
Today it would also be
3/14 1:59:26.5358979
at approximately 1:59:26.5358979 AM or PM.
PI = π
is the ratio of the circumference of a circle to its diameter (or to 2 times its radius) or:
circumference = π. * diameter ( = 2 * π * radius)
The value of PI to 16 digits is...
3.1415926535897932
PI is an irrational number, which means that when you write it as a decimal there is no limit to the number of digits: it is infinitely long. (That's why the time above is approximate.) Here's the value of PI to a million digits:
