Examples:

1. {{Evaldemo|CURRENTDAY|s=is}} displays

   {{ CURRENTDAY}} is 21

2. {{Evaldemo|#expr:2*3}} displays

   {{ #expr:2*3}} gives 6

3. {{subst:evaldemo|subst=subst:|#expr:2*3}} gives:

   {{ subst:#expr:2*3}} gives 6

4. {{Evaldemo|1=#expr:2+2=5}} displays

   {{ #expr:2+2=5}} gives 0

5. {{Evaldemo|1=#expr:(2+2=4)|s==}} displays

   {{ #expr:(2+2=4)}} = 1

6. {{Evaldemo|urlencode:!|s==}} displays

   {{ urlencode:!}} = %21

7. {{Evaldemo|uc:abc}} gives

   {{ uc:abc}} gives ABC

8. {{subst:Evaldemo|uc:Upper Case|subst=subst:}} substitutes

   {{ subst:uc:Upper Case}} gives UPPER CASE

   See Help:Substitution for several caveats wrt subst=subst:.

As always the expression (first parameter) cannot directly contain "|", "=", plus other special cases related to square brackets / curly braces. In the case of this template "not directly" means "never" except from "=" as shown above.

For simple nested expressions use template:Evdn (edit•talk•links•history):

1. {{evdn|#expr:4*|#expr:not 0| >3 | s=yields}} displays

   {{ #expr: 4*{{ #expr:not 0}} >3 }} yields 1

2. {{evdn|urlencode:|DIRMARK}} displays

   {{ urlencode:{{ DIRMARK}}}} gives %E2%80%8E
