Re^2: List all different equations for a given oneby LanX (Canon)

How many random numbers do you need to proof that abs($x**10000001) and abs($x**10000000) are identical? :) Please if you consider replying that you limit the range as soon that one function returns inf think about functions with multiple separated intervals not being inf. I'd rather avoid numerical approaches as long as possible. (IIRC for instance some differential equations can only be solved numerically) Cheers Rolf ( addicted to the Perl Programming Language)
