Thanks to all who responded!

Original question:
 I would like to convert a floating point grid to an integer grid.  I
 have Spatial Analyst and ArcView 8.1 . I would then like to convert
 that integer grid to a point theme.


Dr. Uwe Lange:
did you try aGrid.Truncate, to convert the floating point grid to an
integer grid?


Mathais Tobler:
Use the Int function under Arithmetic in the Map Calculator to create
the integer grid.
The Avenue script below converts the gird to a point theme.

'Creates a point theme from active grid theme cell values.
'Selected cells used, or all if none selected.
'Null cells ignored.
'Adds theme to active view.

'Useful, for example, to do a density analysis.


theView = av.GetActiveDoc

thePrj = theView.GetProjection
theGthm = theView.GetActiveThemes.Get(0)
theGrid = theGthm.GetGrid


'Prompt for theme name

ptName = FileName.GetCWD.MakeTmp("gridpt","shp")
ptName  = FileDialog.Put(ptName, "*.shp", "Save Point Theme")
if (ptName = NIL) then
   exit
end

'Create point theme

ptName.SetExtension("shp")
ptFTab = theGrid.AsPointFTab(ptName,thePrj)
ptThm = FTheme.Make(ptFTab)

'Add the theme to the view...

theView.AddTheme(ptThm)

Joe Martinetti:
In Spatial Analyst you could use the INT request the same way and
then
the AsPointFTab.

Elaine Hallisey Hendrix:

Using the Map Calculator, the command "aGrid.Int" (no quotes, and
aGrid is the name of your input raster) converts each cell of aGrid
to an integer value by truncating at the decimal point.

In the Raster Calculator, click on the double arrow next to Cancel.
Clickin the Int button brings up Int().  Move the cursor inside the
parenthese and double click on the name of your grid.
Int([aGrid])

Bill Huber:
In the map calculator use an expression like

         [My grid].Int

There are then many ways to convert that to a point shapefile.  The
most straightforward probably is to use the Sample request within a
script, as shown below.   The speed is impressive--processing a grid
with 1,000,000 cells took 59 seconds on a two-year old PC here.
Don't try it unless the grid is pretty small (about a million cells
or less)--your system will probably choke on point themes with larger
numbers of records.  Incidentally, this technique does not require
your grid to be an integer grid.

theVTab = (g=g).Sample({g})
theXY = XYName.Make(theVTab,
   theVTab.FindField("X"),
   theVTab.FindField("Y"))
theTheme = Theme.Make(theXY)
theView.AddTheme(theTheme)
' end of example
