Template:Open-open/doc

The open-open template wraps its argument in a left round bracket, right round bracket. These are used to delimit an open-open interval in mathematics, that is one which excludes both the start and end points.

The template uses math to ensure there is no line break in the expression and Greek characters look better. It should only be used on its own in text and not within a math template.

Open-closed and closed-open intervals are liable to be misunderstood and 'fixed' to use round brackets on either side. Use of these templates should warn editors that what is there is what is meant and point to the meaning.

Usage
Use this to wrap an open-open interval. For example:

$(0, 1)$ means greater than zero and less than one.

produces:

$(0, 1)$ means greater than zero and less than one.
