<p>The module provides OpenSCADA for a static standard mathematical functions library.
</p><p>To address the functions of the library you can use the static call address <b>Special.FLibMath.{Func}()</b> or dynamic <b>SYS.Special.FLibMath["{Func}"].call()</b>, <b>SYS.Special.FLibMath.{Func}()</b>. Where <i>{Func}</i> — function identifier in the library.
</p>
