The value of Zeta(3) to 1,000,000 decimal digits. the number is defined as sum(1/n^3,n=1..infinity), the sum of inverses of cubes and equals 1.2020569031…
Computed by : Sebastian Wedeniwski (wedeniws@de.ibm.com) who computed more than 128 million digits using this more efficient formula found by Theodor Amdeberhan and Doron Zeilberger.
