==Description==

==Description==

*This function gives the sign of a number.

*This function gives the sign of a number.

*In <math>SIGN(n)</math>, <math>n </math>, is any real number.  

*In <math>SIGN(Number)</math>, <math>Number </math>, is any real number.  

*Suppose the <math>n</math> value is a positive number ,then this function will return 1.

*Suppose the <math>Number</math> value is a positive number ,then this function will return 1.

*When  <math>n</math> is  a negative number, this function shows -1.   

*When  <math>Number</math> is  a negative number, this function shows -1.   

*Also  <math>n</math> is zero, this function shows 0.

*Also  <math>Number</math> is zero, this function shows 0.

*This function will shows the result as error when the <math>n</math> value is non-numeric.

*This function will shows the result as error when the <math>Number</math> value is non-numeric.

*Also when we are giving the <math>n</math> value with Complex number, then it will consider only the real part of a Complex number.

*Also when we are giving the <math>Number</math> value with Complex number, then it will consider only the real part of a Complex number.
