This C source file is part of TestFloat, Release 2a, a package of programs
for testing the correctness of floating-point arithmetic complying to the
IEC/IEEE Standard for Floating-Point.
 
Written by John R. Hauser.  More information is available through the Web

Derivative works are acceptable, even for commercial purposes, so long as
(1) they include prominent notice that the work is derivative, and (2) they
include prominent notice akin to these four paragraphs for those parts of
this code that are retained.
