        General information about built-in math functions:
        The built-in math functions are categorized into the following:
    </p>
        <p>
      </p>
        <div class="itemizedlist">
          <ul class="itemizedlist" style="list-style-type: disc; ">
            <li class="listitem">A list of built-in functions that have scalar or vector argument versions, and,</li>
            <li class="listitem">A list of built-in functions that only take scalar float arguments.</li>
          </ul>
        </div>
        <p>
    </p>
        <p>
        The vector versions of the math functions operate
        component-wise.  The description is per-component.
    </p>
        <p>
    The built-in math functions are not affected by the prevailing rounding mode in the calling
    environment, and always return the same value as they would if called with the round to
    nearest even rounding mode.
  </p>
        <p>
    The built-in math functions take scalar or vector arguments. For any specific use of these
    function, the actual type has to be the same for all arguments and the return type unless
    otherwise specified.
  </p>
        <p>
    The generic type name <span class="type">gentype</span> is used to indicate that the function can
    take <span class="type">float</span>, <span class="type">float2</span>, <span class="type">float3</span>, <span class="type">float4</span>,
    <span class="type">float8</span>, <span class="type">float16</span>, <span class="type">double</span>, <span class="type">double2</span>,
    <span class="type">double3</span>, <span class="type">double4</span>, <span class="type">double8</span>, or <span class="type">double16</span>
    as the type for the arguments.
  </p>
        <p>
    If extended with <a class="citerefentry" href="cl_khr_fp16.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp16</span></span></a>,
    generic type name <span class="type">gentype</span> may indicate <span class="type">half</span> and
    <span class="type">half{2|3|4|8|16}</span> as arguments and return values.
  </p>
        <p>
    The generic type name <span class="type">gentypef</span> is used to indicate that the function can
    take <span class="type">float</span>, <span class="type">float2</span>, <span class="type">float3</span>, <span class="type">float4</span>,
    <span class="type">float8</span>, or <span class="type">float16</span> as the type for the arguments.

        <h4><a id="id-1.6.11"></a>Half and Native forms</h4>
        <p>
        A subset of Math functions (table 6.8) are defined 
        with the <code class="code">half_</code> prefix. These 
        functions are implemented with a minimum of 
        10-bits of accuracy i.e. an ULP value ≤ 
        8192 ulp.
    </p>
        <p>
        A subset of Math functions (table 6.8) are 
        defined with the <code class="code">native_</code> prefix. These 
        functions may map to one or more native device 
        instructions and will typically have 
        better performance compared to the corresponding 
        functions (without the <code class="code">native__</code>
        prefix). The accuracy (and in some cases the 
        input range(s)) of 
        these functions is implementation-defined.
    </p>
        <p>
        For the half and native forms, we use the 
        generic type name 
        gentype to indicate that the functions 
        (table 6.9) can take 
        <span class="type">float</span>, <span class="type">float2</span>, 
        <span class="type">float3</span>, 
        <span class="type">float4</span>, <span class="type">float8</span>

        Support for denormal values is optional for 
        <code class="code">half_</code> functions. The <code class="code">half_</code> 
        functions may return any 
        result allowed by section 7.5.3, even when 
        <code class="code">-cl-denorms-are-zero</code> (see section 5.8.4.2) is not in 
        force. Support for denormal values is 
        implementation-defined for <code class="code">native_</code> functions.
