I would expect the first to produce the same results as the second, but,
I suppose because of one of floating point's features, it doesn't work
I'm am relatively new to Python but use it daily. Today, I went looking
for a function, like PHP's number_function, that will take a number and
return a string with number formatted with grouped thousands and the
decimal portion rounded to a given number of places. This is certainly
needed
Your code has a little bug, I highly recommend to add a test to your
code, for an idea see below - I fixed your code as well.
#!/usr/bin/env python
import math
def number_format(num, places=0):
Format a number with grouped thousands and given decimal
places
#is_negative = (num 0)
Thanks. I noticed the bugs later. But after talking with my boss, he
suggested something more elegant (again *untested*, yet):
import locale
def number_format(num, places=0)
Format a number according to locality and given places
locale.setlocale(locale.LC_ALL,
This is a little faster:
def number_format(num, places=0):
Format a number according to locality and given places
locale.setlocale(locale.LC_ALL, )
return locale.format(%.*f, (places, num), True)
I tested this ok with my test
