Detailed Description

This class is a leaf of math expression ie either double float long double etc...

A leaf has a symbol which may be the string representation of the value: MATH_LeafExpression::setSymbol() & MATH_LeafExpression:: getSymbol() methods

The evaluation of the leaf is by default the double value of the string of the corresponding value of the symbol in symbol map passed in argument of the method MATH_LeafExpression::evaluate().

A leaf node is insert in the tree by the MATH_LeafExpression::insertInTree()

The method MATH_LeafExpression::setOperator() is to set the operator of which the leaf is one of its argument. The operator found must has the less priority of the operator to set.

The symbol with pre-defined value are

PI (or pi)
E (or e)
