苏先生向BBC新闻记者解释道：“非常有趣，通过一些代数处理，我们的公式就能够跳跃式的计算PI值了；换句话，它允许计算pi的具体数位”。
"Interestingly, by some algebraic manipulations, (our) formula can compute PI with some bits skipped; in other words, it allows computing specific bits of PI," Mr Sze explained to BBC News.
计算机代数系统的处理对象虽然是符号公式，但也需要整数运算，并且需要的是无限精度整数运算。
Although the objects processed by a computer algebra system are usually symbolic formulae, it is necessary for the system to operate with integers and even with infinite integers.
