Re^4: Math::BigFloat and zero

Yes, and I can't find it. My best guess is that Knuth discussed 0⁰ being less securely defined than 0¹, and possibly the author of Math::BigFloat was making a joke on this, but 0E0 is not related to 0⁰ and is very much defined.

"Less securely defined"? It's typically considered to be undefined, considering that: lim x->0 x⁰ = 1 lim x->0 0^x = 0 But of course, any model is free to define 0⁰ to be anything it wants. I prefer 0⁰ == 7. After all 0⁰ == 7 <==> 0 * 0⁰ == 7 * 0 <==> 0¹ == 0 <==> 0 == 0	[reply]
