Python: Configure the rounding to round to the floor, ceiling

Last update on April 24 2025 12:45:22 (UTC/GMT +8 hours)

4. Floor and Ceiling Rounding

Write a Python program to configure the rounding to round to the floor, ceiling. Use decimal.ROUND_FLOOR, decimal.ROUND_CEILING

Sample Solution:

Python Code:

import decimal
print("Configure the rounding to round to the floor:")
decimal.getcontext().prec = 4
decimal.getcontext().rounding = decimal.ROUND_FLOOR
print(decimal.Decimal(20) / decimal.Decimal(6))
print("\nConfigure the rounding to round to the ceiling:")
decimal.getcontext().prec = 4
decimal.getcontext().rounding = decimal.ROUND_CEILING
print(decimal.Decimal(20) / decimal.Decimal(6))

Sample Output:

Configure the rounding to round to the floor:
3.333

Configure the rounding to round to the ceiling:
3.334
