What number is rounded to 1000000?

Answer 1

The answer depends on the degree of rounding.

To the nearest million, any number between 500000 and 1500000.

[the number could be 1499999.997, so the upper limit is NOT 1499999]

To the nearest hundred thousand, any number between 950000 and 1050000

To the nearest ten thousand, any number between 995000 and 1005000

...

To the nearest unit, any number between 999995 and 1000005

To the nearest tenth, any number between 999999.5 and 1000000.5

To the nearest hundredth, any number between 999999.95 and 1000000.05

etc.
