What the hell is 3.14, really? The "why", not the "how".

Yeah… I know. The thing is… anyone worth their salt as a number theorist keeps running into the number 9801, which interestingly HMIE has never mentioned. And an example of the arbitrariness of this formulation… he’s using the decimal point as a multiplication symbol for 3.14 (which isn’t pi!!!), but not for 7.29 which would be 7 * 29. In fact, when i was a teenager, I was so enamored by this number that I always followed my username with 9801, and used it for passwords as well.

aaaaand I stopped reading.
