So there is a real root between -.996 and -.997 and another one between -.999 and -1, in accordance to my guess that real roots (if existing) would be close to -1.

That's of great interest. I am compiling a short HP-71B -Math Pack JPC ROM HP-BASIC code to confirm your observations. This will also indicate me how slow is my device to compute these only 4 values.

But that won't allay my worries; among the 9998 other complex roots, is there not one or the other closer to the point (0,0)?
