In this version it is not enforced that the floating number must have 5 digits after the decimal point
The problem statement can be found here
The calculator has the functionality of adding, subtracting, multiplying, exponentiating, dividing, and differentiating polynomials over one variable x
For the input:
1 x x 2 ^ + 1 x +
x 2 ^ 1.00001 + d
3 2 3 - 1 + /
2 x 2 ^ * 2 /
The program correctly outputs
Parse Error
2 x *
NAN
1 x 2 ^ *
Reduces the polynomial if the denominator is a non zero constant polynomial
Returns Parse Error if error in parsing
Returns NAN if any attempt at division by zero
Added Makefile according to the specification given here
