public real double([real newValue])

Run On

Called

Parameters

newValue
Type: real
The new value; optional.

Return Value

Type: real
The current value.

If you pass in a value that has a different data type than the object, the data type of the object will be changed to match the data type of the value.

A COMVariant object has a double data type if its data type is set to COMVariantType::VT_R8.

The following example creates a new COMVariant object of type VT_R8 and sets the value to 123.456.

{ 
    COMVariant var = new COMVariant( 
        COMVariantInOut::IN_OUT,  
        COMVariantType::VT_R8); 
  
    // Set value of the object 
    var.double(123.456); 
}
