Assuming you are interested only in whole numbers, then it depends upon the nearest to which the number is being rounded:
To the nearest 3 or 4 it is 901
To the nearest 5 or 6 it is 902
To the nearest 9 or 10 it is 904
To the nearest 12 it is 905
To the nearest 15 it is 907
To the nearest 18 it is 908
To the nearest 20 it is 909
To the nearest 25 it is 912
To the nearest 30 it is 914
To the nearest 36 it is 917
To the nearest 45 it is 922
To the nearest 50 it is 924
To the nearest 60 it is 929
To the nearest 75 it is 937
To the nearest 90 it is 944
To the nearest 100 it is 949
To the nearest 150 it is 974
To the nearest 180 it is 989
To the nearest 225 it is 1012
To the nearest 300 it is 1049
To the nearest 450 it is 1124
To the nearest 900 it is 1349
To round a number to the nearest 10, you select from the closest multiple of ten that's higher (900) and the closest that is lower (890). Whenever a number has units of 0,1,2,3,4 you round down, and whenever a number has units of 5,6,7,8,9 you round up. In this case, the units are 5, so you round up, meaning that 895 is 900 when rounded to the nearest 10.
the least number that round to 800000 is 750000 and the greatest number that round to 800000 is 849999.

round number of 2000000 to least and greatest number
the least number that round to 800000 is 750000 and the greatest number that round to 800000 is 849999.
which number will round up to 26000
When rounding to the nearest hundred, half will round down and half will round up, ie 100 ÷ 2 = 50 will round each way. → any number greater than or equal to 900 and less than 900 + 50 = 950 will round down to 900. ie any number n such than 900 ≤ n < 950 will round down to 900 to the nearest 100. Which means your [whole] number could be any of 900, 901, 902, ..., 949.
