Python: Configure the rounding to round up and round down a given decimal value

Python module: Exercise-2 with Solution

Write a Python program to configure the 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

Previous: Write a Python program to construct a Decimal from a float and a Decimal from a string. Also represent the Decimal value as a tuple.
Next: Write a Python program to round a Decimal value to the nearest multiple of 0.10, unless already an exact multiple of 0.05.

Python: Tips of the Day

For-else construct useful when searched for something and find it:

# For example assume that I need to search through a list and process each item until a flag item is found and 
# then stop processing. If the flag item is missing then an exception needs to be raised.

for i in mylist:
    if i == theflag:
        break
    process(i)
else:
    raise ValueError("List argument missing terminal flag.")
