In the example of the Flex and Bison program that we saw in the course, the calculation of the values of the arithmetic expressions was trans formed into Bison and the verification of the values entered was performed using the Flex tool. However, this calculation allows only the manipulation of integer values without taking into consideration the case of real, hexadecimal and octal values. In addition, there is no error handling when there is a division by a zero. The goal of this exercise is to enrich this numerical calculator by adding the possibility of calculating the powers yx, as well as two operators> and The binary operator> (resp. and The binary operator> (resp.
