Really don't wanna be mean... Did you figure that out all by yourself? Do you really think in all this time, nobody has ever suggested this? Read the sticky on top of improvement suggestions first!!
Here in Belgium you should write: 1 000 000, if I recall correctly, it might even that you don't even are allowed to use those spaces, but at school we use this, so I think it's okay. No "." or "," a "," means comma, so after that the tenths are coming
In Sweden, 1.000.000 = one milion and 1,000000 = 1.
It just depends on what country you're from
Rain would be good, but as said above, it's been suggested a lot of times before.
I just looked it up and rain has actually been suggested 1.000.004 times before
let's all agree typing "one million" would make things clear for everybody
Not even just countries. In most parts of Canada, we use "," to seperate our thousands. In Quebec, they use ".". A carryover from France I suspect.
I always wondered how those countries that had it backwards (I mean, the other way around...) handled co-ordinates. (Ie. (2.567.847,373) Because, if you guys use commas instead of decimal places, how would you know what the two values are? Do you use a period to split the two different numbers? Or in such cases do you just not seperate your thousands with a comma at all?
Also note, that 1 000 000 is now recodnized worlwide to avoid the confusion. I don't know if that is how it is taught everywhere, but that is the way engineers have begun to do things to avoid the confusion when values are passed from country to country. (At least, that's how I think it came about, anyways )
