Actually, the code in question is not in the public domain, despite that the term "public domain" is in the comments of SloppyMath.java: /* some code derived from jodk: http://code.google.com/p/jodk/ (apache 2.0) * asin() derived from fdlibm: http://www.netlib.org/fdlibm/e_asin.c (public domain): * ============================================================================= * Copyright (C) 1993 by Sun Microsystems, Inc. All rights reserved. * * Developed at SunSoft, a Sun Microsystems, Inc. business. * Permission to use, copy, modify, and distribute this * software is freely granted, provided that this notice * is preserved. * ============================================================================= */ Nowhere in e_asin.c is it mentioned the file has been released to the public domain. The 1993 block is the actual license from e_asin.c, but examination of it indicates that it should be perfectly fine to use in a Apache 2.0 licensed or non-open-source/free software project. Just leave the notice as-is. If the OP is still concerned, then the OP will have to follow-up with the specific legal concern SloppyMath.java allegedly raises. Saying there is a licensing concern is of little help without providing specifics. --ewh P.S.
