Hello,
New to the list and having a problem with float & round or my lack of understanding.
Basic: I am getting stock prices, it puts it in a list, then I convert it to strings, floating and integers.
The problem I am having is that it converts the string to a float fine. But rounding it off and saving
it as a variable isn't working like I expected.
Examples:
# Original number before conversion was 70.70 as string.
# I get the 3rd item of the list called stock. And rightly so it will print like this.
print "Current Price: %f" % (stock[2])
......
results: Current Price: 70.700000
What I want is for it to print at 70.70, but not be a string, but a float for
math purposes.
I have tried several ways and it won't error, but doesn't do what I want.
Tried:
cp=stock[2]
print round(cp,2)
......
results: 70.7
Above is good and works, but:
cp=stock[2]
print "Current Price: %f" % round(cp,2)
.......
results: Current Price: 70.700000
Same here:
cp=round(stock[2],2)
print "Current Price: %f" % (cp)
.......
results: Current Price: 70.700000
I don't have a problem storing the number AS IS in the database, but would like it to work
the way I thought it should. Maybe the formatting will work better when I pull it from the database
and not from the list. Then again, maybe I am missing something here.
Any help??
Thanks.
