This method only displays the whole number and does not round down the value. Check out the code below: def roundDown(n): return int("{:.0f}".format(n)) roundedValue = roundDown(2.5) print("The rounded value of {} is: {}".format(2.5, roundedValue)) print("Data type of the ...
ROUND_HALF_DOWN 是另一种常见的舍入模式,当小数部分为5时,总是向下舍入。这意味着无论前一位是奇数还是偶数,都会向下舍入。 fromdecimalimportDecimal,ROUND_HALF_DOWN num1=Decimal('1.5').quantize(Decimal('1'),rounding=ROUND_HALF_DOWN)num2=Decimal('2.5').quantize(Decimal('1'),rounding=ROUND_HALF...
So, round() rounds 1.5 up to 2, and 2.5 down to 2!Before you go raising an issue on the Python bug tracker, rest assured you that round(2.5) is supposed to return 2. There’s a good reason why round() behaves the way it does....

Since Python 3.0, round() uses banker's rounding where .5 fractions are rounded to the nearest even number:>>> round(0.5) 0 >>> round(1.5) 2 >>> round(2.5) 2 >>> import numpy # numpy does the same >>> numpy.round(0.5) 0.0 >>> numpy.round(1.5) 2.0 >>> numpy.round(2.5)...
x, y, z = (int(round(x)), int(round(y)), int(round(z))) return (x, y, z) def sectorize(position): """ Returns a tuple representing the sector for the given `position`. Parameters --- position : tuple of len 3 Returns --...
2. Rounding Up/Down Configuration Write a Python program to configure rounding to round up and round down a given decimal value. Use decimal.Decimal Click me to see the sample solution 3. Round to Nearest 0.10 (with 0.05 Exception)
