SIGN(n)

This function gives the sign of a number.
In $SIGN(n)$ , $n$ , is any real number.
Suppose the $n$ value is a positive number ,then this function will return 1.
When $n$ is a negative number, this function shows -1.
Also $n$ is zero, this function shows 0.
This function will shows the result as error when the $n$ value is non-numeric.
Also when we are giving the $n$ value with Complex number, then it will consider only the real part of a Complex number.
