Apparently this is a derivative of DHB classes already included in SciSmalltalk.
Just for the record, my SThub repository is a copy from the first Squeak/Pharo port at http://www.squeaksource.com/DHBNumerical.html in 2011 (I don't know if SciSmalltalk existed then). For those wondering about the book, there is a Google Books copy here:

Thanks for the pointer. Because didier told me that he wants to give it for free (I just resent him a mail about that). Stef
