<H5>Single Value Functions</H5>
The following single value arithmetic functions are available:
<P>
<PRE>
        sin   (e)               sine
        cos   (e)               cosine
        tan   (e)               tangent
        asin  (e)               arc sine
        acos  (e)               arc cosine
        atan  (e)               arc tangent
        deg   (e)               radians to degrees
        rad   (e)               degrees to radians
        ln    (e)               natural logarithm
        exp   (e)               natural exponent
        log10 (e)               base 10 logarithm
        exp10 (e)               base 10 exponent
        int   (e)               integer  part of real
        frac  (e)               fraction part of real
        abs   (e)               absolute value
</PRE>
where:
<P>
<PRE>
          e  can be any arithmetic expression.
          Arguments for trigonometric functions MUST be expressed 
          in radians.
</PRE>
example:
<P>
<PRE>
          int(tan(2.3 * ln(%6)))
