壹 is the formal, financial form of 一 (yī). It appears on checks, invoices, receipts, contracts and banknotes so that nobody can easily alter the amount. Example: 人民币壹佰元 (rénmínbì yībǎi yuán) means "one hundred yuan RMB."

Common mistake: Learners sometimes use 壹 in everyday writing, like 壹个人, which looks odd. In normal text just write 一. Also, do not confuse 壹 with 壶 (hú, pot), which has a similar top but a different bottom.
