Python Math: Round a specified decimal by setting precision

Python Math: Exercise-40 with Solution

Write a Python program to round a specified decimal by setting precision (between 1 and 4).

Sample Solution:

Python Code:

import decimal

d = decimal.Decimal('00.26598')
print("Original Number : ",d)
for i in range(1, 5):
    decimal.getcontext().prec = i
    print("Precision-",i, ':', d * 1)

Sample Output:

Original Number :  0.26598                                                                                    
Precision- 1 : 0.3                                                                                            
Precision- 2 : 0.27                                                                                           
Precision- 3 : 0.266                                                                                          
Precision- 4 : 0.2660
