$(NUCLEUS_DIR)/lib/libm.a #include <math.h>double cosh(double x);
The function or functions documented here may not be used safely in all application contexts with all APIs provided in the ChorusOS 5.0 product.
See API(5FEA) for details.
The cosh() function computes the hyperbolic cosine of x.
The cosh() function returns the hyperbolic cosine, unless the magnitude of x is too large. In that case, errno is set to ERANGE and a system-dependent notification is performed.
