According to the rules of the number, they are rounded to the nearest integer, and if the fractional part of the number is 0.5 , the number is rounded up.

decided in this way, received 100/100 , but I would like to get rid of the number 1000000 , since when entering the number X, 4999999 rounds Up:

from math import *
X = Float (Input ())
a = Floor (x)
b = x - a
if (int (Round (B, 1000000) * 100)) & lt; 50:
  Print (int (x))
ELIF (INT (Round (B, 1000000) * 100)) == 50 OR (INT (ROUND (B, 2) * 100)) & gt; 50:
  Print (Ceil (X))

Answer 1, Authority 100%

If you need to round the numbers in a specific side, then use the following functions

And if you need when a certain residue rounded the number in one direction or another, you can try to use the balance of the division (%) of the two numbers and compare already on it

math.ceil () – rounding numbers to the biggest

math.floor () – rounding numbers to the smaller side

math.trunc () – discard fractional part

def proper_round (num, dec = 0):
  Num = STR (NUM) [: STR (NUM) .INDEX ('.') + Dec + 2]
  IF num [-1] & gt; = '5':
    RETURN FLOAT (NUM [: - 2- (NOT DEC)] + STR (int (NUM [-2- (NOT DEC)) + 1))
  RETURN FLOAT (NUM [: - 1])
