NAME
SoFloatElement -SoFloatElement is an abstract base class for elements that consists of a single float value.
This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple single precision floating point value.
SYNOPSIS
#include <Inventor/elements/SoFloatElement.h>
Inherits SoElement.
Inherited by SoLineWidthElement, SoListenerGainElement, and SoPointSizeElement.

Detailed Description
SoFloatElement is an abstract base class for elements that consists of a single float value.
This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple single precision floating point value.
This element is like a convenient light-weight version of the SoReplacedElement. It differs from the SoReplacedElement in that the set() and get() methods are already implemented, since it is known that subclasses will still contain just a single float value.
