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);
