Last update on December 21 2024 07:34:42 (UTC/GMT +8 hours)

Write a Python program to round a specified number upwards towards infinity and down towards negative infinity with 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
