2512	interval cosh: wrong result if interval contains 0 (but is not identical to [0,0])	stephan.puchegger@…	Boris Gubenko	"The last line (line 179) of the cosh function in the file transc.hpp should imho read:

return I(static_cast<T>(1), rnd.cosh_up(-x.lower() > x.upper() ? x.lower() : x.upper()), true);

instead of

return I(static_cast<T>(0), rnd.cosh_up(-x.lower() > x.upper() ? x.lower() : x.upper()), true);

since the cosh(0) == 1. Otherwise the function will return the wrong result."	Bugs	closed	Boost 1.38.0	interval	Boost 1.37.0	Showstopper	fixed
