I believe the C libraries SoftFloat and fdlibm are suitable for what you are looking for. Others include Linux (GNU libc, glibc) or *BSD libc's math functions. Finally, CRlibm should also be of interest to you.
While technically there are IEEE-754 compliant systems because they do not implement non-required features described in the standard, a reference implementation allowing
access to all rounding modes
support signalling NaNs
support trapping of all five traps
does not exist in the standard languages. This causes recurring woes of William Kahan, the main force behind the standard and its adaption on the Intel processors.
I don't know if there are some esoteric languages which do support them, but I can rule out Java, C#, C++, Fortran.
EDIT: While there is a lack of compiler support, I advise Hausers SoftFloat implementation given by mctylr. Hauser knows what he is doing.
A rather confusing question; in C++ it is assumed this sort of detail is taken care of by the hardware or the compiler. So, in C++ floating-point addition would be
float a = 1.0;
float b = 2.0;
float c = a + b;
I'm sure this is not what you actually meant; perhaps you'd benefit from this page which tries to emulate IEEE-754-compliant hardware in javascript?

我相信 C 库 SoftFloat 和 fdlibm 适合您正在寻找的内容。其他包括 Linux（GNU libc、glibc）或 *BSD libc 的 数学函数。最后，CRlibm 您应该也会感兴趣。
Ulrich Drepper 有一篇有趣的查看不同的数学库，可能也值得一读。

Ulrich Drepper has a interesting look at different math libraries, that might be also worth reading through.
我一定让你失望了：几乎没有。

我不知道是否有一些深奥的语言确实支持它们，
但我可以排除 Java、C#、C++、Fortran。

I must disappoint you: There is practically none.

一个相当令人困惑的问题；在 C++ 中，假设此类细节由硬件或编译器处理。所以，在 C++ 中，浮点加法是
我确信这不是你真正的意思；也许您会受益于此页面，它试图模拟javascript 中的 IEEE-754 兼容硬件？

一种解决办法可以是 python。 python有一个函数可以转换IEEE-754 32/64位精度十六进制浮点
你可以用python编写你的应用程序或者只是创建一个python函数并在C/C++中调用它
我不确定如何从C/调用python C++但这是可能的。 从 C++ 调用 Python 函数
one work around for you could python. python has a function that can convert IEEE-754 32/64 bit precision HEX float point
You can either write you app in python or just create a python function and call it in C/C++
I'm unsure how to call python from C/C++ but it is possible. Calling Python functions from C++
