<!-- ================================ DESCRIPTION  -->

    <refsect1 id="description"><title>Description</title>
        <para>
                Return <constant>sizeof(<type>float<replaceable>n</replaceable></type>)</constant> bytes of data read from location (<emphasis>p</emphasis> + (<varname>offset</varname> * <varname>n</varname>)).
                </para>
        <para>
The <type>half<replaceable>n</replaceable></type> values are read from location (<varname>p</varname> + (<varname>offset</varname> * <varname>n</varname>)) and then converted to single precision floating point.
The read address computed as (<varname>p</varname> + (<varname>offset</varname> * <varname>n</varname>)) must be aligned to <constant>sizeof(<type>half</type>)</constant> * number of <type>half</type> elements being read (given by <varname>n</varname>) bytes.
