To whom it may concern:

I post issue at first time.
Please forgive me if this is rude

C:\Users\kudo-shunsaku>python
Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 18:41:36) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> num = 4.625
>>> "{:.2f}".format(num)
'4.62'
>>> num = 4.645
>>> "{:.2f}".format(num)
'4.64'
>>> num = 4.655
>>> "{:.2f}".format(num)
'4.66'
>>>

Please, check this out.
 I checked it version 3.5.3 and 3.6.1 on Windows and Cent OS.
