MicroTESK’s floating-point functionality is based on Java SoftFloat, which is a Java implementation of the Berkeley SoftFloat library, a free, high-quality software implementation of binary floating-point that conforms to the IEEE Standard for Floating-Point Arithmetic. As the original version, Java SoftFloat fully implements four floating-point formats: 32-bit single-precision, 64-bit double-precision, 80-bit double-extended-precision, and 128-bit quadruple-precision.
Java SoftFloat is distributed under the Apache License, Version 2.0, which implies the freedom to use the software for any purpose (to distribute it, to modify it and to distribute modified versions of the software) under the terms of the license, but requires preservation of the copyright notice and disclaimer.
The current implementation (v1.0) corresponds to SoftFloat Release 2b (2002 May 27).
