Parse as float, then cast to int

[bjester]

Summary

In python:

• if x = 25.5, then int(x) == 25
• if x = '25.5', then int(x) throws an exception
• if x = '25.5', then float(x) == 25.5 and thus int(float(x)) == 25 works for both strings, floats, and ints

Talking with @rtibbles, we don't want to do this. We'll implement a different approach
