A redesign of my Polynomials All in One math tool. Input is handled using a two-part queue string, separated by a colon. Part one indicates the operators, part two the operands. This program can chain operations, can interrupt normal math to find the zeroes (at that point), and supports derivative and integral as well. Repeated exponents and terms out-of-exponent-order do not confuse the program. Fractional coefficients supported. Negative exponents not supported. Error catching for unsupported features, divide by zero, and algorithm failure implemented. In addition, prepend the input string with "W" or "w" to activate this program's "show work" feature. 2.3 - Zeroes finding algorithm fixed. No longer glitches on non-integer coefficients. 2.4 - Zeroes algorithm debugged, steamlined, and optimized. MIssing zeroes fixed. 3.1 - Options menu added. Show work moved here. Prepending input with W now turns off show work for individual polynomials. DCS/Celtic3 saving integrated (silently disables if not present). 3.2 - Zeroes finding algorithm now no longer fails when trailing coefficient(s) are zero. Rather if realizes that this means some power of X is factorable, drops the trailing zeroes, adds 0 to the set of zeroes, then proceeds with rational zeroes test as normal
