Be careful with floating points: a separator can be a point or a comma, and you don't know what separator was used when creating a string. Never expect the separator is always a point or always a comma. You can find a mix of these 2 notations. And generally speaking, a point or a comma inside a string with digits is not necessary a fp separator. As I said previously, StrNumCmp in mainly intended to sort references in list. Most of time, for a component value, you cannot know the meaning of separator You can have 4,7K or 4.7K or 4K7 but also 7400,DIP14 -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
