I think Python was the first to bring this into my consciousness. See this enhancement request, which changed the float-to-string conversion from seventeen significant figures to shortest: https://bugs.python.org/issue1580 https://bugs.python.org/issue1580 After they did that, I learned that Scheme specifies similar behavior. In fact, I think it was added to R4RS after the Steele and White paper. As the article says, this behavior spread across languages, so that it's weird to see something different now.
