Ulp(Double)
Returns the size of an ulp of the argument.
[Android.Runtime.Register("ulp", "(D)D", "")]
public static double Ulp (double d);[<Android.Runtime.Register("ulp", "(D)D", "")>]
static member Ulp : double -> doubleParameters
- d
- Double
the floating-point value whose ulp is to be returned
Returns
the size of an ulp of the argument
- Attributes
Remarks
Returns the size of an ulp of the argument. An ulp, unit in the last place, of a double value is the positive distance between this floating-point value and the double value next larger in magnitude. Note that for non-NaN x, ulp(-<i>x</i>) == ulp(<i>x</i>).
Special Cases: <ul> <li> If the argument is NaN, then the result is NaN. <li> If the argument is positive or negative infinity, then the result is positive infinity. <li> If the argument is positive or negative zero, then the result is Double.MIN_VALUE. <li> If the argument is ±Double.MAX_VALUE, then the result is equal to 2<sup>971</sup>. </ul>
