But as the old chips are not manufactured anymore, this should not be a problem.<br /> <br /> In version 1.11.9.8 a software multiplication is performed so the trig functions can be used on any chip that has enough internal memory.<br /> <br /> In the report file you can find out if your micro supports the HWMUL. the _HWMUL conststant is set to 1 in that case.<br /> <br /> When software multiplication is used, the multiply routine needs more processor cycles. A number of trig functions depend on the multiplication code and as a result, they become more slow too.<br /> <br /> &lt;span style=&quot;font-family: Arial;&quot;&gt;&amp;nbsp;&lt;/span&gt;<br /> <br /> All Trig() functions are supported by the double too!<br /> <br /> &lt;span style=&quot;font-family: Arial;&quot;&gt;&amp;nbsp;&lt;/span&gt;<br /> <br /> &lt;span style=&quot;font-family: Arial;&quot;&gt;{{Languages}}&lt;/span&gt;<br /> <br /> [[Category:Floating_Point/de]]</div>
