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.
