> My contribution: largest-order-first (big endian) makes sense in real life because people tend to make quick judgements in unreliable situations. For example, take the announcement that you're receiving $132551 dollars. You wouldn't want to hear something like "Hello! You have been awarded one and fifty and five hundred and... and one hundred thousand dollars!", you want to hear "You have been awarded One hundred and thirty two thousand and ... dollars!" The largest sums change decisions dramatically so it makes sense they come first.

And yet in Arabic, the numbers are written in order from the least to the most significant digit, even if they are not really pronounced that way, starting from the numbers in the hundreds and up: "1234" is read as essentially "one thousand two hundred four-and-thirty", the same way the German does it. And yes, the order looks like it's the same as in e.g. English, but Arabic is written right to left. So, no, it's absolutely fine to write numbers in little endian even in the language that pronounces it the big-endian or even the mixed-endian way.
