Hi,
I have added a bug 1914
(http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1914). I will commit
the chanhes before the 4.10.0 release.
Thanks

Hi,
We have a patch for the SLD rendering for the colormap. It seems that it is
documented to take doubles, but all floats passed via SLD become ints through
use of atoi.
This patch only takes care of the ColorMap. This allows color rendering of
float values.

If some change could work into 4.10, that would be great.
Cheers,
Rob
