Subject: v.surf.rst wrong quant
Platform: GNU/Linux/i386
grass obtained from: CVS
grass binary for platform: Compiled from Sources
The quant result from query of elevation data computed by v.surf.rst (and s.surf.rst) is not correct
testquant4 in cent, quant (326)
testquant4 in cent, actual (327.380127)
(should be 327)
The problem may be in
lib/rst/interp_float/output2d.c
G_quantize_fp_map_range (params->elev, mapset,
(DCELL) zminac - 0.5, (DCELL) zmaxac + 0.5,
(CELL) (zminac - 0.5), (CELL) (zmaxac + 0.5));
This bug might have been there for years. Other parameters
are quantized correctly.
