This method reads the start tag, the contents of the element, and moves the reader past the end element tag. It expands entities and ignores processing instructions and comments. The element can only contain simple content. That is, it cannot have child elements.

The reader attempts to convert the element content to a single-precision floating point number according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.
