	<title>Logarithmes</title>
    
    <p>Les logarithmes peuvent être calculées avec la <link xref="function">fonction</link> log.</p>
    <example>
    <p>log 100</p>
    </example>
    <p>
    To calculate a logarithm in a different base use a <link xref="superscript">subscript number</link> or normal number after the function.
    </p>
    <example>
    <p>log₂ 32</p>
    <p>
    log2 (32)
    </p>
    <p>
    log (32;2)
    </p>
    </example>
    <p>Pour calculer le logarithme népérien utilisez la fonction ln.</p>
    <example>
    <p>ln 1,32</p>
    </example>
    <p>
    Euler's number can be entered by using the <link xref="variable">constant</link> e.
    </p>
    <example>
    <p>e^1,32</p>
    </example>
