| [InsertAfter(EquationNodeType equationType)](./insertafter/) | Inserts the specified node after the current node. |
| [InsertBefore(EquationNodeType equationType)](./insertbefore/) | Inserts the specified node before the current node. |
| [InsertChild(int32_t index, EquationNodeType equationType)](./insertchild/) | Inserts a node of the specified type at the specified index position in the current node's child node list. |
| [IsNull()](./isnull/) const | Checks whether the implementation object is nullptr. |
| explicit [operator bool()](./operator_bool/) const | operator bool() |
| [operator=(const EquationNode\& src)](./operator_asm/) | operator= |

## Examples


```cpp
Aspose::Cells::Startup();
// Instantiate a Workbook object that represents Excel file.
Workbook workbook;

// Adds an equation object to the worksheet.
TextBox textBox = workbook.GetWorksheets().Get(0).GetShapes().AddEquation(1, 0, 1, 0, 100, 300);

// Gets the starting node of the equation object
EquationNode mathNode = textBox.GetEquationParagraph().GetChild(0);

// Inserts a fractional equation.
FractionEquationNode node = (FractionEquationNode)mathNode.AddChild(EquationNodeType::Fraction);
node.SetFractionType(EquationFractionType::Skewed);

U16String str1 = u"A";
EquationComponentNode numerator = (EquationComponentNode)node.AddChild(EquationNodeType::Numerator);
TextRunEquationNode TR = (TextRunEquationNode)(numerator.AddChild(EquationNodeType::Text));
TR.SetText(str1);

U16String str2 = u"B";
EquationComponentNode denominator = (EquationComponentNode)node.AddChild(EquationNodeType::Denominator);
TR = (TextRunEquationNode)(denominator.AddChild(EquationNodeType::Text));
TR.SetText(str2);


//Save the excel file.
workbook.Save(u"exmaple.xlsx");

Aspose::Cells::Cleanup();
```
