是否有JavaScript的十进制数学库？ [英] Is there a decimal math library for JavaScript?

问题描述

是否有一个成熟的库可以在JavaScript中进行基于十进制的数学运算，可能是任意精度的？

Is there a mature library for doing decimal-based math, possibly arbitrary-precision, in JavaScript?

推荐答案

有一个Java的端口 BigDecimal class（我想它就在这里： http：// freshmeat。 net / projects / js_bigdecimal / 很长一段时间。我很久以前就看过它，看起来很麻烦而且很庞大，但是（如果那是我正在考虑的那个）它已经被用作一些加密工具的一部分，所以它有可能工作正常。

There's been a "port" of the Java BigDecimal class (I think it's here: http://freshmeat.net/projects/js_bigdecimal/ ) for a long time. I looked at it a long time ago and it seemed kind-of cumbersome and huge, but (if that's the one I'm thinking of) it's been used as part of some cryptography tools so there's a decent chance that it works OK.

因为密码学很可能是需要这些东西的地方，所以这是窥探这些软件包的好方法。

Because cryptography is a likely area to generate a need for such things, that's a good way to snoop around for such packages.
