任何可用于在浮点表示之间转换的C ++库？ [英] Any C++ libraries available to convert between floating point representations?

问题描述

我最近需要解释一个DEC 32位浮点表示。它不同于分配给指数和尾数的位数的IEEE浮点表示。

I recently had a need to interpret a DEC 32-bit floating point representation. It differs from the IEEE floating point representations in the number of bits allocated to the exponent and mantissa.

这里是一组浮点格式的描述：

Here's a description of a bunch of floating point formats:

我设法滚动我自己的C ++代码，将一个DEC 32位浮点数填入IEEE 32位浮点数，但是想知道是否

I managed to roll my own C++ code to stuff a DEC 32-bit float into an IEEE 32-bit float but was wondering if there were any libraries out there that had tackled this conversion and others already.

我选中了 boost.org ，但没有看到任何内容。

I checked boost.org but didn't see any in there.

You mean like libvaxdata?

我从来没有使用它 - 我只是发现它通过谷歌。但它看起来像你要找的。

I've never used it - I just found it by googling. But it looks like what you're looking for.

这是一个C库，而不是C ++，但是转换浮点数据应该在externC调用中正常工作。

It's a C library rather than C++, but converting floating point data should work fine from extern "C" calls.
