Package Overview for Berkeley SoftFloat Release 3e
==================================================
John R. Hauser<br>
2018 January 20
Berkeley SoftFloat is a software implementation of binary floating-point
that conforms to the IEEE Standard for Floating-Point Arithmetic. SoftFloat
is distributed in the form of C source code. Building the SoftFloat sources
generates a library file (typically `softfloat.a` or `libsoftfloat.a`)
containing the floating-point subroutines.
The SoftFloat package is documented in the following files in the `doc`
subdirectory:
* [SoftFloat.html](http://www.jhauser.us/arithmetic/SoftFloat-3/doc/SoftFloat.html) Documentation for using the SoftFloat functions.
* [SoftFloat-source.html](http://www.jhauser.us/arithmetic/SoftFloat-3/doc/SoftFloat-source.html) Documentation for building SoftFloat.
* [SoftFloat-history.html](http://www.jhauser.us/arithmetic/SoftFloat-3/doc/SoftFloat-history.html) History of the major changes to SoftFloat.
Other files in the package comprise the source code for SoftFloat.
