- <h3 class="subsection">D.11.1 <code>math</code> library operators</h3>
- <p>The unary operators take a single real number to a real result. They
- <a name="index-trigonometric-functions"></a>
- include
- </p>
- <table><tr><td> </td><td><pre class="example">ceil floor round trunc
- sin cos tan sinh cosh tanh
- asin acos atan asinh acosh atanh
- exp log sqrt cbrt expm1 log1p fabs
- </pre></td></tr></table>
- <p>The binary operators take a pair of real numbers <code>(<var>x</var>,<var>y</var>)</code> to
- a single real number output. They include
- </p>
- <table><tr><td> </td><td><pre class="example">pow hypot atan2 remainder bus vid add sub mul div
- </pre></td></tr></table>
- <p>where the last four correspond to the C language operators <code>+</code>,
- <code>-</code>, <code>*</code>, and <code>/</code>. The functions named <code>bus</code> and
- <code>vid</code> are like the <code>sub</code> and <code>div</code> functions,
- respectively, with the order of the operands reversed, as explained in
- <a href="complex.html#complex"><code>complex</code></a>.
- </p>
- <p>The meanings of these operators are documented in the GNU <code>libc</code> reference
- manual or other C language references. They follow IEEE standards including
- proper handling of <code>nan</code> and infinity.
