I like this one:
a = b (definition) a^2 = ab (multiply both sides with a) a^2 - b^2 = ab - b^2 (substract b^2) (a - b)(a + b) = b(a - b) (factor) a + b = b (delete the same terms) 2b = 1b (since a equals b) 2 = 1  has the same flaw as mjordan's, btw. |

Strange, MJ, that problem was on another forum I haunt in the last couple weeks.

Trolls only, eh? Suits ya.
I've known about that one for a while - pretty clever. Anyway, back to converting an integer to a polynomial... to the OP: best think about what you're trying to do. It sure as hell ain't "converting", whatever that's supposed to mean. It might be integrating, as pal suggests... |

what i meant by integer to polynomial is: suppose you have a very big number that can't be represented by a built-in integer data type. so you can take this number as a string, convert to a polynomial, do the operations like addition and than convert the result to a string and print. sth like 19375343 is 1*x^7 +9*x^6+....+4*x^1+3*x .

Why would you use a string? Just make your own datatype:
class ReallyLong
{
long number[8];
// insert code to manage stuff
} |

Shoot, if that's what you need, why don't you just get a bignum library?
