Fn.Log
Returns the logarithm to a given base.
Syntax
Fn.Log(Base:RAT,X:RAT):RAT
Description
This function returns the logarithm of X to the base Base rounded to the current global accuracy.
@param Base The base to which to compute the logarithm.
@param X The value of which to compute the logarithm.
@return The logarithm of X to the base Base rounded to the current global accuracy.
Example
Fn.SetAccuracy(20); R := Fn.Log(3,27); Dec(R, 40); 3 -------------------------------
Example
Fn.SetAccuracy(20); R := Fn.Log(2,10); Dec(R, 40); 3.32192809488736234787 -------------------------------
