The round takes its value to the nearest even integer.

To round up, use the math.ceil:

import math
print(math.ceil(1.5))  # 2.0
print(math.ceil(2.5))  # 3.0

To round 0.5 up and 0.49999 down, you can do a function with the module decimal:

import decimal

def arredondar(x):
    return int(decimal.Decimal(x).quantize(0, decimal.ROUND_HALF_UP))

print(arredondar(1.5))  # 2
print(arredondar(2.5))  # 3
print(arredondar(1.4))  # 1
print(arredondar(2.4))  # 2

  • But then I can’t do what I want. I want to enter a number and if the house after the '.' is less than 4 round down and if it is greater than 5 round up. You’d know how I can do that ?
