It's 8.8MB of plaintext English output describing the ridiculously long number, for those on mobile (who can't see the full file), or who don't want to click through the 'file is truncated...' link

As an approximation, one could just say three duoquinquagintacentillinonagintacentillion

Isn't "one hundred thousand factorial" a more useful conversion? Would your conversion ever find utility?

Aside, this is why French style punctuation with a space before ? or ! is superior.

I did not write it to be useful. I just wanted to say it can handle large integers.

I am implementing the XPath standard. The standard says there need to be a function to convert integers to English, but it does not specify an upper limit on the integers

Cool, IMO that makes it potentially useful (but being useful isn't required of course).

Out of curiosity, what part of the spec does that implement? Is it to do with fn:format-integer.

Here is the function standard: https://www.w3.org/TR/xpath-functions-31/#func-format-intege...

Number formatting is really complicated
