Option 1 (fast but unsafe): Pick a special int value that is rarely used, e.g. typemin(Int). Option 2 (works with all types, including Float64, and is safer): Use a nullable type. This might complicate your code and may slightly increase your memory usage. -erik -- Erik Schnetter <[email protected]> http://www.perimeterinstitute.ca/personal/eschnetter/
