They work OK for small arguments but for example atan(4) is in gross error. However the functions atanf(x) and tanf(x) works as good substitutes. We use #define tan tanf ..etc as a workaround in the file math.h Hope this will be corrected in the beta 17 release //Gunnar -- ============================================= Gunnar Isaksson Hamradio: SM5IUF Internet: Gunnar DOT Isaksson AT saab DOT se _____________________________________________ - For help on using this list, send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
