## Fn.LogN

Returns the logarithm to a given base with a given accuracy.

### Syntax

Fn.LogN(Base:RAT,Val:RAT,Acc:INT):RAT

### Description

This function returns the logarithm of `Val` to the base `Base` rounded to the given accuracy `Acc`.

@param

*Base*The base to which to compute the logarithm.@param

*Val*The value of which to compute the logarithm.@param

*Acc*The desired accuracy.@return The logarithm of

`Val`to the base`Base`rounded to accuracy`Acc`.

#### Example

R := Fn.LogN(3,27, 30); Dec(R, 40); 3 -------------------------------

#### Example

R := Fn.LogN(2,10, 30); Dec(R, 40); 3.321928094887362347870319429489 -------------------------------
