Sign Function
System.Math
Sign(value
)
value
(required; any numeric type, including Decimal)A numeric expression
Integer
Determines the sign of a number
The return value of the Sign function is
determined by the sign of value
, as
follows:
If number is |
Sign returns |
---|---|
Positive |
1 |
Zero |
0 |
Negative |
-1 |
Sign is useful in cases in which the sign of a quantity defines the sign of an expression. For example:
lngResult = lngQty * Sgn(lngValue)
This is a Shared member, so it can be used without creating any objects.
If you are using the Sign function to evaluate a
result to False
(0) or True
(any nonzero value), you could use the CBool
function instead.
A major use for Sign is to determine the sign of an expression.
The name of this function has changed. In VB 6, it is named Sgn. In VB.NET, it is named Sign and is a member of the Math class of the System namespace.
