--NOTES | |||
-- | |||
-- NOTE A1: This template calculates the inflated value of a given | |||
-- currency amount based on nation code and a range of years. | |||
-- | |||
-- NOTE F2: The optional format parameters, fmt=c and fmt=eq, can be | |||
-- used to simply display commas or a typical "equivalent to" | |||
-- phrase which can help provide clarity of calculated amounts. | |||
-- For option "fmt=eq": "equivalent to $1,000 in 2013". | |||
-- In text, the year can be specified just once to both compute | |||
-- the inflated value and show the year in the phrase. Many | |||
-- pages have formatted the result with Template:Formatprice. | |||
-- | |||
-- NOTE V3: The parameters are validated to show error messages, for | |||
-- invalid amounts or years outside the range of supported years. | |||
-- Previously, invalid year caused "NaN" ("not a number") which | |||
-- could confuse users to wonder why using an actual number in | |||
-- the amount or year range would be called "NaN". | |||
