Python Math: Round a specified number upwards towards infinity and down towards negative infinity

Python Math: Exercise-41 with Solution

Write a Python program to round a specified number upwards towards infinity and down towards negative infinity of precision 4.

Sample Solution:-

Python Code:

import decimal
context = decimal.getcontext()
value = decimal.Decimal(1) / decimal.Decimal(17)
print("1/17 = ",value)
context.prec = 4
print("Precision: ",4)

context.rounding = getattr(decimal, 'ROUND_CEILING')
value = decimal.Decimal(1) / decimal.Decimal(17)
print("Round upwards towards infinity: ",value)

context.rounding = getattr(decimal, 'ROUND_FLOOR')
value = decimal.Decimal(1) / decimal.Decimal(17)
print("Round down towards negative infinity: ",value)

Sample Output:

1/17 =  0.05882352941176470588235294118                                                                       
Precision:  4                                                                                                 
Round upwards towards infinity:  0.05883                                                                      
Round down towards negative infinity:  0.05882

Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++"
str.strip()

print(str)

Output:

+++Welcome python+++
