The +calculations in step four are implied in the transformations, for +example when the @option{--average} option is used. + +At the core, however, Ledger is basically a sophisticated calculator +with special knowledge about commoditized values. It knows what you +mean if you add ten dollars to twenty euros, and later ask for the +balance of that particular account. So it follows that first we must +discuss how Ledger deals with math, and from there move on to describing +how the steps above are achieved. + + + $classes + + NSMutableString + NSString + NSObject + + $classname + NSMutableString + + + $class + + CF$UID + 33 + + NS.keys + + + CF$UID + 11 + + + CF$UID + 12 + + + NS.objects + + + CF$UID + 13 + + + CF$UID + 30 + + + + NSParagraphStyle + NSFont + + $class + + CF$UID + 29 + + NSAlignment + 4 + NSLineHeightMultiple + 1.1000000238418579 + NSTabStops + + CF$UID + 14 + + + + $class + + CF$UID + 28 + + NS.objects + + + CF$UID + 15 + + + CF$UID + 17 + + + CF$UID + 18 + + + CF$UID + 19 + + + CF$UID + 20 + + + CF$UID + 21 + + + CF$UID + 22 + + + CF$UID + 23 + + + CF$UID + 24 + + + CF$UID + 25 + + + CF$UID + 26 + + + CF$UID + 27 + + + + + $class + + CF$UID + 16 + + NSLocation + 28 + + + $classes + + NSTextTab + NSObject + + $classname + NSTextTab + + + $class + + CF$UID + 16 + + NSLocation + 56 + + + $class + + CF$UID + 16 + + NSLocation + 84 + + + $class + + CF$UID + 16 + + NSLocation + 112 + + + $class + + CF$UID + 16 + + NSLocation + 140 + + + $class + + CF$UID + 16 + + NSLocation + 168 + + + $class + + CF$UID + 16 + + NSLocation + 196 + + + $class + + CF$UID + 16 + + NSLocation + 224 + + + $class + + CF$UID + 16 + + NSLocation + 252 + + + $class + + CF$UID + 16 + + NSLocation + 280 + + + $class + + CF$UID + 16 + + NSLocation + 308 + + + $class + + CF$UID + 16 + + NSLocation + 336 + + + $classes + + NSArray + NSObject + + $classname + NSArray + + + $classes + + NSParagraphStyle + NSObject + + $classname + NSParagraphStyle + + + $class + + CF$UID + 32 + + NSName + + CF$UID + 31 + + NSSize + 14 + NSfFlags + 16 + + Courier + + $classes + + NSFont + NSObject + + $classname + NSFont + + + $classes + + NSDictionary + NSObject + + $classname + NSDictionary + + + $classes + + KBWordCountingTextStorage + NSTextStorage + NSMutableAttributedString + NSAttributedString + NSObject + + $classname + KBWordCountingTextStorage + + + $class + + CF$UID + 36 + + NS.time + 267380389.45634499 + + + $classes + + NSDate + NSObject + + $classname + NSDate + + + $classes + + NSMutableArray + NSArray + NSObject + + $classname + NSMutableArray + + + $top + + Snapshots + + CF$UID + 1 + + + $version + 100000 + + -- cgit v1.2.3
