            The <code class="function">remquo</code> function computes the value <code class="varname">r</code> such
that <code class="varname">r</code> = <code class="varname">x</code> - <code class="varname">n</code>*<code class="varname">y</code>, where <code class="varname">n</code> is the integer nearest the
exact value of <code class="varname">x</code>/<code class="varname">y</code>. If there are two integers closest
to <code class="varname">x</code>/<code class="varname">y</code>, <code class="varname">n</code> shall be the even one. If <code class="varname">r</code> is zero, it is
given the same sign as <code class="varname">x</code>. This is the same value
that is returned by the <a class="citerefentry" href="remainder.html"><span class="citerefentry"><span class="refentrytitle">remainder</span></span></a> function.</p>
        <p><code class="function">remquo</code> also calculates the lower seven bits of the
integral quotient <code class="varname">x</code>/<code class="varname">y</code>, and gives that value the same
sign as <code class="varname">x</code>/<code class="varname">y</code>. It stores this signed value in the object
pointed to by <code class="varname">quo</code>.

            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. 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>, or <span class="type">float16</span> as the type for the arguments. For 
            any specific use of these function, the actual type has to be the same for all 
            arguments and the return type.
        </p>

            generic type name <span class="type">gentype</span> may indicate <span class="type">double</span> and
            <span class="type">double{2|3|4|8|16}</span> as arguments and return values. If extended with
