			Built-in integer functions can be used to take scalar or vector arguments. We use
the generic type name <span class="type">gentype</span> to indicate that the function can take <span class="type">char</span>, <span class="type">char{2|4|8|16}</span>, <span class="type">uchar</span>, <span class="type">uchar{2|4|8|16}</span>, <span class="type">short</span>, <span class="type">short{2|4|8|16}</span>, <span class="type">ushort</span>, <span class="type">ushort{2|4|8|16}</span>, <span class="type">int</span>, <span class="type">int{2|4|8|16}</span>, <span class="type">uint</span>,
<span class="type">uint{2|4|8|16}</span>, <span class="type">long</span>, <span class="type">long{2|4|8|16}</span>, <span class="type">ulong</span>, or <span class="type">ulong{2|4|8|16}</span> as
the type for the arguments. We use the generic type name <span class="type">ugentype</span> to refer to unsigned
versions of <span class="type">gentype</span>. For example, if <span class="type">gentype</span> is <span class="type">char4</span>, <span class="type">ugentype</span> is <span class="type">uchar4</span>.</p>
        <p>For any specific use of a function, the actual type has to be the same for all arguments and the return type unless otherwise specified.
