(... to be explained more clearly )<br /> OK will be used in test column to confirm that this property has been coded and testing code have been added in 2.9<br /> NO i.e. no more supported in 2,9<br /> {| width=&quot;97%&quot; border=&quot;1px&quot;<br /> !Function<br /> !1,5+<br /> !Math<br /> lib<br /> !Eval<br /> Math<br /> !Calc<br /> !coded<br /> !tested<br /> !Explanation<br /> |-<br /> |abs<br /> | #<br /> | #<br /> | #<br /> | #<br /> |<br /> |<br /> |Absolute value<br /> |-<br /> |acos<br /> | #<br /> | #<br /> | #<br /> | #<br /> |<br /> |<br /> |Arc cosine -- output in radians.<br /> |-<br /> |acosh<br /> | #<br /> | #<br /> | #<br /> | #<br /> |<br /> |<br /> |Inverse hyperbolic cosine -- output in radians.<br /> |-<br /> |asin<br /> | #<br /> | #<br /> | #<br /> | #<br /> |<br /> |<br /> |Arc sine -- output in radians.<br /> |-<br /> |asinh<br /> | #<br /> | #<br /> | #<br /> | #<br /> |<br /> |<br /> |Inverse hyperbolic sine.-- output in radians.<br /> |-<br /> |atan2<br /> | #<br /> | #<br /> |<br /> |<br /> |<br /> |<br /> |Arc tangent of two variables -- pass in two values like (y, x), and you'll get the atan(y/x), adjusted to the proper quadrant.
