是否有任意精度浮点库的C / C ++允许任意精度指数？ [英] Is there an arbitrary precision floating point library for C/C++ which allows arbitrary precision exponents?

问题描述

我正在寻找一个用于C / C ++的任意精度浮点库（简单C是首选）。我需要任意精度指数。 GMP和MPFR使用固定大小的指数，因此它们不合格（我有一些解决方法的想法，但我更喜欢开箱即用的解决方案）。如果指数精度可以自动调整以防止无穷大值，这将是一个很好的功能。

I'm looking for an arbitrary precision floating point library for C/C++ (plain C is preferred). I need arbitrary precision exponents. GMP and MPFR use fixed size exponents, so they are ineligible (I have some ideas for workarounds, but I prefer an out-of-the-box solution). It would be an nice feature if the exponent precision can be adjusted automatically to prevent infinity-values.

如果你确定这样的库不存在，请说所以。

If you know for sure that such an library does not exist, please say so.

推荐答案

据我所知，没有像GMP / MPFR那样的主流。但Fredrik Johansson的 arb 包含一个名为 fmpr的模块提供任意精度指数的浮点数。

There is nothing as mainstream as GMP/MPFR as far as I know. But Fredrik Johansson's arb contains a module called fmpr that provides floating-point numbers with arbitrary precision exponents.
