1. obsolete To calculate the figures of one's financial accounts. The morning after another rather indulgent evening, I decided it was high time for me to cast up my accounts.

2. obsolete To regurgitate. A play on the terms cast (which is an obsolete term for calculating arithmetical operations, here meaning "to throw") and accounts (one's bank account, here referring to one's stomach). The gentleman, deeply inebriated, cast up his accounts onto the head of some poor wretch sleeping in the street.
