"ISO 8601 week dates %G, %g, and %V yield values calculated from the week-based year defined by the ISO 8601 standard. In this system, weeks start on a Monday, and are numbered from 01, for the first week, up to 52 or 53, for the last week. Week 1 is the first week where four or more days fall within the new year (or, synonymously, week 01 is: the first week of the year that contains a Thursday; or, the week that has 4 January in it). When three of fewer days of the first calendar week of the new year fall within that year, then the ISO 8601 week-based system counts those days as part of week 53 of the preceding year. For example, 1 January 2010 is a Friday, meaning that just three days of that calendar week fall in 2010. Thus, the ISO 8601 week-based system considers these days to be part of week 53 (%V) of the year 2009 (%G); week 01 of ISO 8601 year 2010 starts on Monday, 4 January 2010." %g as "shortest representation of a float" is from (s)printf format specifiers. -----Ursprüngliche Nachricht----- Von: sqlite-users [mailto:sqlite-users-boun...@mailinglists.sqlite.org] Im Auftrag von Simon Slavin Gesendet: Montag, 16.

Can you tell me where your %G and %g definitions are coming from ? I thought %g was for printing the shortest representation of a number.
