I'm trying to round numbers derived from cmath's divide function to a "whole" number, the results often being negative due to the nature of the program.
Example code:
strength = input("Input Strength Stat: ")
str_mod = round(strength/2)
However, the result of this is that it, due to an oddity in python, always returns closer to zero rather than further if, say str_mod prior to rounding ends up at something like -1.5 (resulting in -1 rather than -2 as desired)
This, since I'm trying to create an automatic derived stat calc script for a custom Pen and Paper RPG system, is not the desired behavior. What I desire is for the script to return, at -1.5, -2.0 upon rounding. I need to be able to do this while still rounding positive numbers up similarly.
You could do this the safe way:
strength = float(raw_input("Input Strength Stat:"))
str_mod = round(strength/2)
In this case, since strength is guaranteed to be a float, you can safely divide by 2 without worrying about truncation or importing division from __future__. As a bonus, you remove a huge security liability in your game as well.
Using input, a user could do some serious damage to your system:
RPG console> Input Strength Stat: __import__('os').system('rm -r ~')
#^ User input (don't try this!)
