price precisions don't influence display precision; balancing is based on display precision (#23) Like ledger, price amounts are now "unobserved", ie their precision does not affect the canonical display precisions used when displaying amounts, and transaction balancing is done based on display precision, ie amounts are considered to balance if their sum appears to be zero when using the canonical display precision. 2010-11-15 01:44:37 +03:00			`# http://code.google.com/p/hledger/issues/detail?id=23`
