I posted a note previous with modest reponse. In the hope that a better link will provoke some more reaction, I am reposting. As promised recently, I am presenting a draft of proposals for math functions which are needed for even most elementary statistics. I have been encouraged to submit this to both the C and C++ Standard Library groups at the same time. (They seem to speaking more than in the past). These are additions to the list drawn up by Walter Brown accepted into TR-1. The style and format follows his closely even though there were some opposition to them from the C++ community. However I think we have to accept that C and C++ compatibility are valued more than C++ 'ideality', and not try to re-open this area of dissent. The draft has been uploaded to the files area in a new folder Math Functions as "More Mathematical Functions.pdf" 220 kb. It is accessible at: http://tinyurl.com/357a6 be grateful if some CVS whizz would copy it to the sandbox as I know that many are unable to access the files section. It would be useful to have comments on 1 Typographical mistakes. 2 Mathematical mistakes (prepared by someone with seriously rusty math!). 3 The choice of functions espcially if there are any your feel strongly are missing, or are not needed (say why). 4 The choice of names. Clarity is preferred to curtness. 5 The choice of names for derivatives like the inverse and complement. I have added suffixes _inc and _c (or _com?). ( for C there will be suffixes f and l for the float and long double versions). Thanks.
