@embrown I liked the idea. Can you fix the style?

@embrown is just for the doc? Makes the code look silly, like we don't know about default values.

@doutriaux1 Yeah, it was primarily for the doc. When sphinx went through to generate the function prototype for this one, it spit out that full range of numbers inside the prototype, which looked horrible.
Thank you for merging!

@doutriaux1 @embrown it would have been nice to fix the bad white space before merging.

[doutriaux1]

yes... it will be merged next time
