如何在 Python 中舍入浮点数？

Question

I know there are different questions like this; and I searched my question on stackoverflow and many other webs, and basically the easiest way to do this is using the round/2 function, but the round function didn't work properly... Here's part of my code using the round function:

ad=150
ad_percent = 75
ap=150
ap_percent=55
armor_pen=35
enemy_armor=125
enemy_max_hp=1000

ap = ap_percent * ap / 100
ad = ad_percent * ad / 100

armor_less = armor_pen * enemy_armor / 100
enemy_armor = enemy_armor - armor_less
# Till now, all is good.

round(ad)
print(ad)

Output

112.5

So... It's not working. How can I make that variable round to 113?

Thanks for helping.

Answer 1

round() returns the rounded value ; it doesn't modify its argument (indeed, it couldn't, in Python's data model (unless __round__ on a custom object had been modified to mutate the object itself, but that would be very, very icky, and I digress)).

You'll need to assign the return value of round() , in other words eg

ad = round(ad)

instead.

Answer 2

You are properly rounding but you are not storming it in a variable to print afterwards.

You can try:

print(round(ad))

Or:

ad_rounded = round(ad)
print(ad_rounded)

Hope it helps. Let me know if it did.
