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

Sample Solution:

Python Code:

import decimal
print("Configure the rounding to round up:")
decimal.getcontext().prec = 1
decimal.getcontext().rounding = decimal.ROUND_UP
print(decimal.Decimal(30) / decimal.Decimal(4))
print("\nConfigure the rounding to round down:")
decimal.getcontext().prec = 3
decimal.getcontext().rounding = decimal.ROUND_DOWN
print(decimal.Decimal(30) / decimal.Decimal(4))
print("\nConfigure the rounding to round up:")
print(decimal.Decimal('8.325').quantize(decimal.Decimal('.01'), rounding=decimal.ROUND_UP))
print("\nConfigure the rounding to round down:")
print(decimal.Decimal('8.325').quantize(decimal.Decimal('.01'), rounding=decimal.ROUND_DOWN))

Sample Output:

Configure the rounding to round up:
8

Configure the rounding to round down:
7.5

Configure the rounding to round up:
8.33

Configure the rounding to round down:
8.32
