MathBabbler morphs into RoadHacker on Pi Day and hits the highway. RoadHacker morphs into MathBabbler when Pi moments occur on Pi Day.

The BAB Driving U.S. Highway 180 on Pi Day 2008 explains the U.S. Highway 180 and Pi Day connection and it includes the 2-day roadtrip plan for Pi Day 2008.

MathBabbler copied the following Pi Day idea from WikiHow.com.

"Simply use 3.14 as a unit of measure. Instead of being 31 years old, you are 9pi years old (approaching your 10th birthday)."MathBabbler on Pi Day 2008 was 74 days away from turning 51 years young and the WikiHow webpage titled "How to Celebrate Pi Day" prompted us to create the following Pi Years function.

the factor Pi is recorded to 2-digits (rounded) beyond the 1st occurrence of 0 in the Pi-digits. f(a) = (a)/3.1415926535897932384626433832795029 PiYears f(50.8) = (50.8)/3.1415926535897932384626433832795029 = 16.17014 Each output is recorded to 2-digits (rounded) beyond the 1st occurrence of 0 in the PiYears decimal digits.On Pi Day 2008, MathBabbler was 16.17014 Pi years young.

`Calculate your age in Pi years.`

[Exercise]## Update::2008.07.09

While working on a BAB for Ringo Starr's 68th birthday, MathBabbler (at the age of 51) wrote a C++ program to convert a number into Pi years.

PiYears(68) = 21.6451 PiYears(51) = 16.2338
