# Sign

Menu Path : **Operator > Math > Arithmetic > Sign**

The **Sign** Operator calculates the sign of the input and returns whether the input is positive, negative, or 0:

- If **X** is greater than 0, the result is 1.
- If **X** is less than 0, the result is -1.
- If **X** is 0, the result is 0.

For example, an input of (0.3, 0.4, -5) outputs (1, 1, -1).

This Operator accepts a number of input values of various types. For the list of types this Operator can use, see [Available Types](#available-types). This Operator always returns a value in the same type as its input.
