  > 46,255 mm²

To be clear: that's the thousandths separator, not the Nordic decimal. It's the size of a cat, not the size of a thumbnail.

*thousands, not thousandths, right?

The correct number is fourty six thousand, two hundred and fifty five square mm.

or about 0.23 furlongs

More like one thousanth percent of an acre.

(wow, that is not much?)

Whoa, I just realized that the comma is the thousands separator when writing out the number in English words.

This is why space is the only acceptable thousands/grouping separator (a non-breaking space when possible). Avoids any confusion.

46_255

Space is also confusing! Then it looks like two separate numbers.

Underscore (_) is already used as a decimal separator in programming languages and Mathematics should just adopt it, IMO.

A competing format to simplify things?

A competing format that is understandable to probably everybody.

An ISO 8601 date is also comprehensible to anybody even if they never seen it before and have to figure it out themselves.

Comprehensible?

I said date. Not time, not timestamp, not period, not week, not range, not ordinal date.

Just date.

You mean thousands separator, yes? Agreed, it’s annoying when languages don’t have this feature.

Ah yes, thousands separator.

A thin non-breaking space also clears up the confusion without the visual clutter of the underscore. It's just inconvenient to use

The problem is our primitive text representation online. The formatting should be localized but there’s not a number type I can easily insert inline in a text box.

Thanks, I was acutally wondering how would someone even manage to make that big a chip.

It's a whole wafer. Basically all chips are made on wafers that big, but normally it's a lot of different chips, you cut the wafer into small chips and throw the bad ones away.

Cerebras has other ways of marking the defects so they don't affect things.
