Fn.Root
Returns the N-th root of a given value.
Syntax
Fn.Root(X:RAT,N:INT):RAT
Description
This funcion returns the N-th root of X rounded to
the current global accuracy.
@param X The value of which to take the N-th root.
@param N The degree of the root to be taken.
@return Returns the N-th root of Val rounded to the current global accuracy.
Example
Fn.SetAccuracy(20); R := Fn.Root(8, 3); Dec(R, 40); 2 -------------------------------
Example
Fn.SetAccuracy(20); R := Fn.Root(-8, 3); Dec(R, 40); -2 -------------------------------
Example
