Checksum and length: 748D 24
Flags Used:
Flag 0 is used to remember if the root is real or complex (that is, to remember the
sign of
d). If d is negative, then flag 0 is set. Flag 0 is tested later in the program to
assure that both the real and imaginary parts are displayed if necessary.
Remarks:
The program accommodates polynomials of order 2, 3, 4, and 5. It does not
check if the order you enter is valid.
The program requires that the constant term
a
0
is nonzero for these polynomials. (If
a
0
is 0, then 0 is a real root. Reduce the polynomial by one order by factoring out
x.)
The order and the coefficients are
not preserved by the program.
