[vtkusers] precision

[Vincent MEYER]

Hi vtkusers,

I've got scalars like below in a vtk file format.

SCALARS ro1 float
LOOKUP_TABLE LookupTable1
899.999607106
899.999522519
...

I use a vtkDataSetReader to read that file and when I do the command below, 
max0 and min0 are rounded to 900.

set range0 [[Reader0 GetOutput] GetScalarRange]
	set min0 [lindex $range0 0]
	set max0 [lindex $range0 1]

How can I say to the reader that I want a much higher precision?

Thanks a lot

Vincent
