This article is about a function from ApCoCoA-1. |

## Fn.RootN

Returns the `N`-th root of a given value with a given accuracy.

### Syntax

Fn.RootN(Val:RAT,N:INT,Acc:INT):RAT

### Description

This functions returns the `N`-th root of `Val` rounded

to the given accuracy `Acc`

@param

*Val*The value of which to take the`N`-th root.@param

*N*The degree of the root to be taken.@param

*Acc*The desired accuracy.@return Returns the

`N`-th root of`Val`rounded to accuracy`Acc`.

#### Example

R := Fn.RootN(8, 3, 30); Dec(R, 40); 2 -------------------------------

#### Example

R := Fn.RootN(-8, 3, 30); Dec(R, 40); -2 -------------------------------
