Python Math: Round up a number to specified digits

Python Math: Exercise-69 with Solution

Write a Python function to round up a number to specified digits.

Sample Solution:-

Python Code:

import math

def roundup(a, digits=0):
    n = 10**-digits
    return round(math.ceil(a / n) * n, digits)

x = 123.01247
print("Original  Number: ",x)
print(roundup(x, 0))
print(roundup(x, 1))
print(roundup(x, 2))
print(roundup(x, 3))

Sample Output:

Original  Number:  123.01247                                                                                  
124                                                                                                           
123.1                                                                                                         
123.02                                                                                                        
123.013
