<h2>Conversions between radians, degrees and gradians</h2>
<dl>
<dt>degtodeg(deg; min; sec)</dt>
<dd>This function converts degrees from the long format with degrees, minutes and seconds to degrees.<br>
For example: degtodeg(12; 30; 0)=12.5</dd>
<dt>degtorad(deg; min; sec)</dt>
<dd>This function converts degrees in the long format (degrees, minutes, seconds) to radians.<br>
degtorad(12; 30; 0)=0.218166...</dd>
<dt>degtograd(deg; min; sec)</dt>
<dd>This function converts degrees in the long format (degrees, minutes, seconds) to gradians<br>degtograd(12; 30; 0)=13.888...</dd>
<dt>degtorad(deg)</dt>
<dd>This function converts degrees to radians<br>degtorad(12.5)=0.218166...</dd>
<dt>degtograd(deg)</dt>
<dd>This function converts degrees to gradians<br>degtograd(12.5)=13.8888...</dd>
<dt>radtodeg(rad)</dt>
<dd>This function converts radians to degrees<br>radtodeg(pi)=180</dd>
<dt>radtograd(rad)</dt>
<dd>This function converts radians to gradians<br>radtograd(pi)=200</dd>
<dt>gradtorad(grad)</dt>
<dd>This function converts gradians to radians<br>gradtorad(400)=6.2831....=2*pi</dd>
<dt>gradtodeg(grad)</dt>
<dd>This function converts gradians to degrees<br>gradtodeg(100)=90</dd>
