BAII-plus 普通版和专业版有区别么？

从FM考纲上抄下来的一句话，注意红色部分，用意自行体会。
Although several different calculators are allowed for this exam, the BAII Plus or Plus Professional are strongly recommended due to their ability to solve for interest rates. There may be examination problems that require the BAII Plus in order to find the answer.
