Conjugated cosh and sinh
by Vladimir V. Kisil 08 Apr '11

08 Apr '11

Dear All, Analysing a failure of my code I found the reason in the absence of conjugate() method for cosh and sinh functions. Is there a fundamental reason for this? Or shall I prepare a patch defining them similarly to this: static ex cosh_conjugate(const ex & x) { // conjugate(cosh(x))==cosh(conjugate(x)) return cosh(x.conjugate()); } Best wishes, Vladimir -- Vladimir V.

[PATCH] Fix unsigned character bugs in ginac-1.5.8
by Martin Guy 06 Apr '11

06 Apr '11

Hi There are a couple of bugs that stop ginac from working on machines whose characters are unsigned by default (where a conversion to int goves a value 0-255). It's the classic "char c = getchar(); if (c == EOF)" with result that it doesn't detect EOF on unsigned machines, or exits prematurely on signed machines if it reads a character 255. The fixes are to replace "char" with "int" so that all 257 possible return values are correctly handled. The attached patch for ginac-1.4.3 still applies to 1.5.8 Cheers M
