= SGN(number)

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.

  x = SNG(-42)
