WP34s: SLVQ implementation  Dieter  10092011 I just noticed that SLVQ may return results with slight errors even in relatively simple cases: 1 ENTERWith 39 internal digits a correct 16digit result should be no problem. So what's going on here?

Re: WP34s: SLVQ implementation  Marcus von Cube, Germany  10092011 If I'm not mistaken, SLVQ is not implemented natively but in user code (XROM). So the normal roundoff errors may occur.
Re: WP34s: SLVQ implementation  Paul Dale  10092011 Solve is a user code program so much work isn't carried out in high precision (some is still). It also searches at display accuracy (i.e. using the approximately equal test). Thus, some lower order digits errors are to be expected.
