![]() Convert to DateTime by adding the calculated average as Return Convert::ToChar( Convert::ToUInt16( CalcNLimitAverage( Char::MinValue, Char::MaxValue, provider ) ) ) Virtual Char ToChar( IFormatProvider^ provider ) Return Convert::ToByte( CalcNLimitAverage( Byte::MinValue, Byte::MaxValue, provider ) ) Virtual Byte ToByte( IFormatProvider^ provider ) true if any element of the dataset is nonzero. For arithmetic or geometric mean averaging, ToBoolean is Return (UnBoxDouble( data ) != 0.0 || UnBoxDouble( data ) != 0.0) Return avg > max ? max : avg Count TypeOfAverage ) Limit the range, based on the minimum and maximum values Get the format provider and calculate the average.ĪverageInfo^ avgInfo = GetAverageInfo( provider ) ĭouble avg = Average( avgInfo->TypeOfAverage ) Calculate the average and limit the range.ĭouble CalcNLimitAverage( double min, double max, IFormatProvider^ provider ) Get the AverageInfo object from the caller's format provider,ĪverageInfo^ GetAverageInfo( IFormatProvider^ provider )ĪvgInfo = static_cast(provider->GetFormat( AverageInfo::typeid )) Return (UnBoxDouble( data ) + UnBoxDouble( data )) / 2.0 Return Math::Sign( SumProd ) * Math::Pow( Math::Abs( SumProd ), 1.0 / data->Count ) This calculation will not fail with negative ![]() This method calculates the average of the object's elements.įor ( int Index = 0 Index Count Index++ ) This property returns the number of elements in the object. Throw gcnew InvalidOperationException( " Index out of range." ) Get, set, and add values with this indexer property. Add additional values with this method. Construct the object and add an initial list of values.ĭata = gcnew ArrayList( (Array^)values ) ĭefaultProvider = gcnew AverageInfo( AverageType::ArithmeticMean ) arithmetic mean, geometric mean, or median. ![]() return an average of the array elements in one of three types: This class encapsulates an array of double values and implements ![]() Use this property to set or get the type of averaging. Virtual Object^ GetFormat( Type^ argType ) if an object of AverageInfo type is requested. This method returns a reference to the containing object Specify the type of averaging in the constructor. Ref class AverageInfo: public IFormatProvider The class instance determines the type of Pass an instance of this class to methods that require an Define the types of averaging available in the class The IFormatProvider object determines how elements are discarded for this calculation. This method returns true if any of the non-discarded array values are non-zero. An object of each class is passed to the ToBoolean(Object, IFormatProvider) method. Objects of the class that implements IConvertible hold an array of Double values. The following example defines a class that implements IConvertible and a class that implements IFormatProvider. The conversion of value to a Boolean is not supported. Value does not implement the IConvertible interface. ' The example displays the following output: array^ numbers = gcnew array ", number, result) The following example converts an array of SByte values to Boolean values. Returns the specified Boolean value no actual conversion is performed.Ĭonverts the value of the specified 64-bit signed integer to an equivalent Boolean value. Overloads ToBoolean(SByte)Ĭonverts the value of the specified 8-bit signed integer to an equivalent Boolean value.Ĭonverts the specified string representation of a logical value to its Boolean equivalent, using the specified culture-specific formatting information.Ĭonverts the value of the specified object to an equivalent Boolean value, using the specified culture-specific formatting information.Ĭonverts the value of the specified 64-bit unsigned integer to an equivalent Boolean value.Ĭonverts the value of the specified 32-bit unsigned integer to an equivalent Boolean value.Ĭonverts the value of the specified 16-bit unsigned integer to an equivalent Boolean value.Ĭonverts the specified string representation of a logical value to its Boolean equivalent.Ĭonverts the value of the specified single-precision floating-point number to an equivalent Boolean value.Ĭonverts the value of a specified object to an equivalent Boolean value.Ĭonverts the value of the specified decimal number to an equivalent Boolean value.Ĭonverts the value of the specified 32-bit signed integer to an equivalent Boolean value.Ĭonverts the value of the specified 16-bit signed integer to an equivalent Boolean value.Ĭonverts the value of the specified double-precision floating-point number to an equivalent Boolean value.Ĭalling this method always throws InvalidCastException.Ĭonverts the value of the specified 8-bit unsigned integer to an equivalent Boolean value. Converts a specified value to an equivalent Boolean value.
