Cannot use int on fractions. Workaround? Python

I am loading in random lines from a CSV into a class. I need the system to see one of those values as a number and not a string to use for calculations. This works fine for whole numbers.

class Weapon:
    def __init__ (self, name, value, damage, weight, properties, catagory, description):
        self.name = name
        self.value = int(value)
        self.damage = damage
        self.weight = weight
        self.properties = properties
        self.catagory = catagory
        self.description = description

I have a problem where if I try to use int on a fraction (for example 0.05) I get the following error:

    self.value = int(value)
ValueError: invalid literal for int() with base 10: '0.05'

What can I use instead of Int, or as well as int, to get it working?

Use 

from decimal import Decimal
int(Decimal(value))

Don't use floats, floats are ugly.

Use int(float(value)) to first parse the string into a float, then convert to an int.

But of course, then 0.05 will be reduced to 0. If that's not OK with you, just use float(value).
