Detailed Description

Factory for creating an ExpressionNode representing '/'.

Some basic simplification is applied to the resulting Node.

Member Function Documentation

MathParser\Parsing\Nodes\Factories\DivisionNodeFactory::makeNode	(		$leftOperand,
			$rightOperand
	)

Create a Node representing '$leftOperand/$rightOperand'.

Using some simplification rules, create a NumberNode or ExpressionNode giving an AST correctly representing '$leftOperand/$rightOperand'.

Simplification rules:

• To simplify the use of the function, convert integer params to NumberNodes
• If $leftOperand is a NumberNode representing 0, return 0
• If $rightOperand is a NumberNode representing 1, return $leftOperand
• If $leftOperand and $rightOperand are equal, return '1'

Parameters

Node | int	$leftOperand	Numerator
Node | int	$rightOperand	Denominator

Return values

Node

Implements MathParser\Parsing\Nodes\Interfaces\ExpressionNodeFactory.

MathParser\Parsing\Nodes\Factories\DivisionNodeFactory::numericFactors (   $leftOperand,   $rightOperand  )

protected

Simplify division nodes when factors are numeric.

Parameters

Node	$leftOperand
Node	$rightOperand

Return values

Node|null
