# How to reduce all value above certain value using Raster Calculator?

I have a raster with elevations above 2000m that I want to "cut" to 1800m.

I cannot quite figure out the correct string and most simple way to do this in the ArcGIS 9.3 raster calculator.

I tried to ceiling function without much luck; would an expression similar to IF([my_raster]>2000,1800,[my_raster]) do the trick?

Con("myraster" > 2000, 1800, "myraster")
