<p>trans.ops - Transcendental Opcodes</p>
<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>Addition library of operations to perform various transcendental operations such as logarithmics and trigonometrics.</p>
<p>To use this library of ops,
add this directive to your PIR:</p>
<pre> .loadlib 'trans_ops'</pre>
<dl>

><b>acos</b>(out NUM, in NUM)</a></dt>
Set $1 to the arc cosine (in radians) of $2.
<dt><a name="asec(out_NUM,_in_NUM)"
><b>asec</b>(out NUM, in NUM)</a></dt>
Set $1 to the arc secant (in radians) of $2.
<dt><a name="asin(out_NUM,_in_NUM)"
><b>asin</b>(out NUM, in NUM)</a></dt>

<dt><a name="atan(out_NUM,_in_NUM,_in_NUM)"
><b>atan</b>(out NUM, in NUM, in NUM)</a></dt>
The two-argument versions set $1 to the arc tangent (in radians) of $2.The three-argument versions set $1 to the arc tangent (in radians) of $2 / $3, taking account of the signs of the arguments in determining the quadrant of the result.
<dt><a name="cos(out_NUM,_in_NUM)"
><b>cos</b>(out NUM, in NUM)</a></dt>
Set $1 to the cosine of $2 (given in radians).
