Re: Factorials of rational numbers up to 999.9

You are mixing Math::Compex and bignum. I'm not really sure that that's well-supported. Have you looked at removing the use of one or the other? I would assume that using only Math::Complex should be sufficient.

A call to ->_cartesian() is issued from within Math::Complex, so my guess is that somewhere somehow, methods from Math::Complex are issued against Math::BigInt objects that may or may not come from bignum. This may be a bug in Math::Complex, but I don't know.

without using bignum the script works fine, but the factorials become #INF at 143!	[reply]

Most likely this is because not all elements in your calculations are Math::Complex objects, especially the constants. I would try to convert all elements to Math::Complex objects, or remove all Math::Complex calculations in favor of Math::BigInt. I'm not sure what part Math::Complex plays in your calculations. Maybe you can eliminate Math::Complex in favor of number pairs, `(Math::BigInt, Math::BigInt)`, to denote the real and imaginary parts.	[reply] [d/l]
