Not sure about in an audio engineering context, but to a layperson in the United States at least, yards are rarely used as a unit outside of American Football. AF is a very popular sport, and yards are displayed with decimal points frequently when talking about statistics related to the sport. I'd say that your average person in this country wouldn't think it was strange to see yards represented with a decimal point, but generally we are used to seeing feet + inches, or feet paired with a fraction.
For example:
0.5 yards represented as 1 ft. 6" or 1 1/2 ft.
