RE: HP 11C real root finder [Newton Method]
Namir, sorry that I was not able to express myself clearly. I wanted to point out that I do not think it's a good idea to use h = 0,01 or 0,001 for any value below 1. This may lead to significant errors since h may be much, much larger than x. For instance, if x = 1E10, h = 1E3 is not recommended. Here, h = 1E13 should be better.
That's why I prefer to set h = 0,001 x or similar. With the only exception x=0 where x may be 0,001.

Using the expression for h ensures that if x=0, h is not zero. This can be coded this way, for instance: Code: X=0? Or even more elegant on the 34s: Code: X=0? Dieter
