Sgn
Returns an integer indicating the sign of a number.
Synopsis
Sgn(number)
Arguments
The number argument can be any valid numeric expression.
Description
The Sgn function has the following return values:
| If Number Is | Sgn Returns |
|---|---|
| Greater than zero | 1 |
| Equal to zero | 0 |
| Less than zero | –1 |
The sign of the number argument determines the return value of the Sgn function. If number is the empty string ("") or a non-numeric value, Sgn returns 0. Sgn resolves multiple sign values; for example, --7 is equivalent to +7, and thus returns 1.
Examples
The following example uses the Sgn function to determine the sign of a number:
Dim MyVar1, MyVar2, MyVar3
MyVar1 = 12: MyVar2 = -2.4: MyVar3 = 0
Println Sgn(MyVar1) ' Returns 1.
Println Sgn(MyVar2) ' Returns -1.
Println Sgn(MyVar3) ' Returns 0.
Println Sgn("") ' Returns 0.
Println Sgn("a") ' Returns 0.See Also
