42. Local and Default Decimal Precision

Write a Python program to get the local and default precision.

Sample Solution:

Python Code:

import decimal
with decimal.localcontext() as context:
    context.prec = 2
    print('Local precision:', context.prec)
    print('22/7 =', (decimal.Decimal('22') / 7))

print()
print('Default precision:', decimal.getcontext().prec)
print('22 /7 =', (decimal.Decimal('22') / 7))

Sample Output:

Local precision: 2                                                                                            
22/7 = 3.1                                                                                                    
                                                                                                              
Default precision: 28                                                                                         
22 /7 = 3.142857142857142857142857143
