[ferret_users] Fill nearest

[Brockmann Patrick <Patrick.Brockmann@xxxxxx>]

Hi all,

I come back on this question because I have received no explanation
to this simple example trying to explain a FNR transform.

yes? let A={4,-1E+34,6}
yes? def axis/x myx1={1,2,5}
yes? let B=A[gx=myx1@asn]
yes? let C=B[x=@FNR]
yes? list B, C
            X: 0.5 to 6.5
Column  1: B is A[GX=MYX1@ASN]
Column  2: C is B[X=@FNR]
            B     C
1   / 1:  4.000  4.000
2   / 2:   ....  5.000
5   / 3:  6.000  6.000

In my understanding, C should be 4,6,6 instead of 4,5,6.
I think this is a bug and I suspect that FNR and FLN act the same way.
Can this be confirmed ?
It would also be logic that FNR always gives a nearest value,
even when points are equally spaced around the missing point.

Tested with ferret v6.61
