So if Pi is an irrational number, and therefore has an infinite line of numbers after the decimal point; my intuition tells me it would take an infinite amount of time to determine its exact value.(adsbygoogle = window.adsbygoogle || []).push({});

a) Do calculators and computers somehow know Pi's exact value or is it just an estimate?

b) Are mathematicians out there that concern themselves with finding ever more accurate definitions of pi? Does at some point it become moot, and no practical application requires such accuracy?
