The Biblical example has been removed for some reason (possibly for not quite matching this trope), I'll dump it here:
- The Bible describes the equipment of the Solomon's temple in 1 Kings 7. Verse 23 reads: "He made the Sea of cast metal, circular in shape, measuring ten cubits from rim to rim and five cubits high. It took a line of thirty cubits to measure around it." Giving the approximate value of pi as three.

"For the record, odds are that your computer "knows" pi to the nearest multiple of 2^-62, about 2.168 * 10^-19, so about eighteen reliable digits." This needs a little more explanation to be less esoteric - even to an engineer and math tutor in this case.

When your computer calculates that (or anything), it uses the RAM. If for example, you have 2 gigabytes of RAM (which is typical), it can, at most, use 2GB = 2048MB = 2097152KB = 2147483648 Bytes = 17179869184 binary places (like decimal places, but in base 2). Actually, half that amount, because one of the binary digits will be a positive or negative sign. I don't know exactly how much bits does the floating point take, so it might be even less bits. There is simply no more room in the RAM to work with, unless you save it all to the hard disk, clear the RAM and go from there - that's what the article means by "make your own storage". I hope I was clear. I hope that I was right (though I expect to be unless there is an even stricter limit somewhere that I don't know about).
