How to get NaN when I divide by zero
python
Solution
The easiest way to get this behaviour is to use `numpy.float64` instead of Python default `float` type:
>>> import numpy
>>> numpy.float64(1.0) / 0.0
inf
Of course this requires NumPy. You can use `numpy.seterr()` to fine-tune the error handling.
Problem
When I do floating point division in Python, if I divide by zero, I get an exception: ``` >>> 1.0/0.0 Traceback (most recent call last): File "<stdin>", line 1, in <module> ZeroDivisionError: float division ``` I'd really like to get `NaN` or `Inf` instead (because the `NaN` or `Inf` will propagate through the rest of my calculation correctly and not kill my program). How can I do this?
