The convention I've known of is different from that you described. "One thousand zero five"(一千零五)means 1005 for me and literally everybody I've known of. "One thousand zero zero five" is something I haven't heard/seen of, and to express 1050 we would say "one thousand zero five ten/one thousand zero fifty"(一千零五十), "fifty" being expressed as "five ten" in Chinese. That is, any numbers of zeros between two nonzero digits are compressed into only one "zero", and there doesn't exist any special rule about zeros at the end; you can say we then only read nonzero digits together with their position/location.Rui wrote:Chinese speakers differentiate numbers as used in years and just regular numbers too. "1998" would be "one nine nine eight year" (一九九八年) or "one thousand nine hundred ninety eight" (一千九百九十八). It gets fun when there are zeros involved, though, as any zero between 2 non-zero digits is said, but any zero afterwards is not. Thus "1,050" is read as "one thousand zero five"( 一千零五) while "1,005" is "one thousand zero zero five" (一千零零五). As years, those would be "one zero five zero" and "one zero zero five" respectively (一零五零 and 一零零五).Terra wrote:(Also, numbers are deceptively complex in English; There's different ways to read the same number depending on whether it's an amount or a year. For example, how does one read 1998? If it's a year: "nineteen ninety-eight", if it's an amount: "one-thousand nine-hundred ninety-eight". For a Chinese speaker, it's even more complex, because in Chinese, numbers are separated every 4 digits instead of every 3 digits.)
English has the added complexity that in certain cases, numbers in the thousands can be stated as an amount of hundreds ("I have fifteen hundred dollars")
204,1203,3500,0320 is "[[two hundred zero four] ten-thousand, one thousand two hundred zero three] hundred-million, [three thousand five hundred] ten-thousand, zero three hundred two ten" (两百零四万一千两百零三亿三千五百万零三百二十), brackets being only aid I added to help Western users better understand the grouping system of numbers in Chinese, and commas only to match the commas used with the Arabic number. The number separated in Western tradition is 204,120,335,000,320.
BTW I don't think the 4-digit comma-split practice is taught in China. When numbers are split by comma I always saw them done in the Western, 3-digit-a-comma way, which (used in Chinese is a useless distraction) has actually annoyed me a lot >.>
