How big is BIGINT?

As I was trying to decide if a bigint column would hold enough values to store historical data in a database, and storage problems aside, this helped me put it into perspective, and decide that, yes, for now, bigint would be big enough for me.

eighteen quintillion, four hundred forty six quadrillion, seven hundred forty four trillion, seventy three billion, seven hundred nine million, five hundred fifty one thousand, six hundred fifteen

Some perspective:
~ 1 trillion pennies (click for details) (Sear’s Tower, Empire State Building & others for scale)

~ 1 Quadrillion pennies (click for details)

~ 1 Quintillion pennies (click for details)

 

BIGINT provides 18.446 quintillion unique values.
