Rounding to two decimal places in Python 2.7?

Question

Using Python 2.7 how do I round my numbers to two decimal places rather than the 10 or so it gives?

print \"financial return of outcome 1 =\",\"$\"+str(out1)         


        

Answer 1

A rather simple workaround is to convert the float into string first, the select the substring of the first four numbers, finally convert the substring back to float. For example:

>>> out1 = 1.2345
>>> out1 = float(str(out1)[0:4])
>>> out1

May not be super efficient but simple and works :)

Answer 2

When we use the round() function, it will not give correct values.

you can check it using, round (2.735) and round(2.725)

please use

import math
num = input('Enter a number')
print(math.ceil(num*100)/100)

Answer 3

You can use str.format(), too:

>>> print "financial return of outcome 1 = {:.2f}".format(1.23456)
financial return of outcome 1 = 1.23
