Returns the arcsine of a given value.
This function returns the arcsine of
X rounded to the current
global accuracy. The domain of this functions ranges between -1
and 1.
- @param X Value of which to compute the arcsine.
- @return The arcsine of X rounded to the current global accuracy.
Fn.SetAccuracy(20);
R := Fn.ArcSin(1/2);
Dec(R, 30);
