Python rounds a number, but I want the number to be exact

Question

I have written a calculator in python that calculates mean, median, and mode. However, I'm having trouble with the "mean" calculation. I do the addition, subtraction, and division, but when I print it out, Python rounds the output, instead of giving me the exact number. For example, if I ask it to find the mean of 5 and 6, the answer should be 5.5, but it says it's 5. Here's the code:

print "How many numbers do you wish to use?"
numofnum = input()
print "Now, put in your numbers."
num1 = input()
num2 = input()
sumofnum = num1 + num2
meanans = sumofnum / numofnum
print "Your answer is %f" % (meanans)

What am I doing wrong?

You are probably using integers and need to use floats instead... — DrCord, May 08 '15 at 23:45

Python's integer division floors the result. You'll have to convert one of your operands to a float type with float(some_number).

Thanks! This was quite a frustrating problem. – Golden Mist May 09 '15 at 00:05
There are two other possibilities mentioned in the accepted answer for the duplicate: use Python 3, or use `from __future__ import division`. – Teepeemm May 09 '15 at 14:26
