Returns the arccosine of a given value.
Syntax
Fn.ArcCos(X:RAT):RAT
Description
This function returns the arccosine 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 arccosine.
@return The arccosine of X rounded to the current global accuracy.
Example
Fn.SetAccuracy(20); R := Fn.ArcCos(1/2); Dec(R, 30); 1.04719755119659774615 -------------------------------
