Signum(Double)
Returns the signum function of the argument; zero if the argument is zero, 1.
[Android.Runtime.Register("signum", "(D)D", "")]
public static double Signum (double d);[<Android.Runtime.Register("signum", "(D)D", "")>]
static member Signum : double -> doubleParameters
- d
- Double
the floating-point value whose signum is to be returned
Returns
the signum function of the argument
- Attributes
Remarks
Returns the signum function of the argument; zero if the argument is zero, 1.0 if the argument is greater than zero, -1.0 if the argument is less than zero.
Special Cases: <ul> <li> If the argument is NaN, then the result is NaN. <li> If the argument is positive zero or negative zero, then the result is the same as the argument. </ul>
