If one or both expressions are Null expressions, the result is Null. If both expressions are Empty, the result is an integer subtype. However, if only one expression is Empty, the other expression is returned unchanged as a result.

Arithmetic operators are shown in descending order of precedence. Parentheses can be used to control the order in which operators are evaluated. The default order, however, frequently achieves the correct result. While it is possible to do date math with dates considered as a number of days (e.g., IncubationDays = SymptomDateTime – ExposureDateTime), the behavior of the database services underlying Epi Info makes it more efficient to use time interval functions (e.g., IncubationDays = MINUTES(ExposureDateTime, Symptom DateTime)/[24*60]). For doing date math, the following rules apply: Date + Date produces Date Example READ {.ProjectsSampleSample.prj}:Surveillance DEFINE var1 NUMERIC ASSIGN var1=1250 MOD 100 DEFINE var2 NUMERIC ASSIGN var2=1+1 DEFINE var3 NUMERIC ASSIGN var3=2-1 DEFINE var4 NUMERIC ASSIGN var4=1*1 DEFINE var5 NUMERIC ASSIGN var5=8/4 DEFINE var6 NUMERIC ASSIGN var6=5^2 LIST var1 var2 var3 var4 var5 var6 ComparisonsDescription
