===== SGN ✓ =====

===== SYNTAX =====
     = SGN(number)

==== PURPOSE ====


The ''SGN'' function is a very simple but useful mathematical function. Its main 
function is to determine the sign of a number. In other words, ''SGN'' tells you 
whether a number is positive, negative, or zero. So, it returns 1 if number 
is positive, 0 if ''number'' is zero and -1 if ''number'' is negative.

You can use ''SGN'' inside an ''IF'' condition to perform different actions 
depending on the sign of a number, and in some cases, ''SGN'' can make your 
code more concise and readable.




==== EXAMPLE ====
    x = SNG(-42)
