Template:Plus if pos
Jump to navigation
Jump to search
Adds a plus sign in front of a number if it's positive. Also accepts mathematical expressions. Example:
{{plus if pos | 2 + 3 }}
Result:
+5
This is useful when calculating some modifier. For example:
{{hidden code| {{#lvardef: dex | 14 }} {{#lvardef: dex_mod | {{plus if pos | floor({{#lvar:dex}} / 2) - 5 }} }} }} Your Dexterity Modifier is: {{#lvar:dex_mod}}
Result:
Your Dexterity Modifier is: +2
(Note: Don't be confused by use of Template:Hidden code in the example; it's an unrelated trick for using variable definitions without causing empty paragraphs.)
