I'm at the sprints at PyCascades and was looking for an issue to work on and came across this and wanted to know more about it. As I was doing some research, I found the terms "narrower" and "wider" to seem ambiguous. I'm assuming "narrower" to mean that an integer has a more precise value and "wider" to mean that a float has a less precise/wider range of possible values, but unless I'm missing something, it isn't clear. I think the first paragraph should be revised to make the meaning more explicit. Happy to assist (with some input), if applicable.
