NAME
sinh, sinhf, sinhl - hyperbolic sine function SYNOPSIS
c99 [ flag... ] file... -lm [ library... ] #include <math.h> double sinh(double x); float sinhf(float x); long double sinhl(long double x); DESCRIPTION
These functions compute the hyperbolic sine of x. RETURN VALUES
Upon successful completion, these functions return the hyperbolic sine of x. If the result would cause an overflow, a range error occurs and +-HUGE_VAL, +-HUGE_VALF, and +-HUGE_VALL (with the same sign as x) is returned as appropriate for the type of the function. If x is NaN, a NaN is returned. If x is +-0 or +-Inf, x is returned. For exceptional cases, matherr(3M) tabulates the values to be returned by acos() as specified by SVID3 and XPG3. ERRORS
These functions will fail if: Range Error The result would cause an overflow. If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the overflow floating-point exception is raised. The asinh() function sets errno to ERANGE if the result would cause an overflow. USAGE
An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before calling these functions. On return, if fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is non-zero, an exception has been raised. An application should either examine the return value or check the floating point exception flags to detect exceptions. An application can also set errno to 0 before calling asinh(). On return, if errno is non-zero, an error has occurred. The asinhf() and asinhl() functions do not set errno. ATTRIBUTES

NAME
cosh, coshf, coshl - hyperbolic cosine function SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <math.h> double cosh(double x); float coshf(float x); long double coshl(long double x); DESCRIPTION
These functions compute the hyperbolic cosine of their argument x. RETURN VALUES
Upon successful completion, these functions return the hyperbolic cosine of x. If the correct value would cause overflow, a range error occurs and cosh(), coshf(), and coshl() return the value of the macro HUGE_VAL, HUGE_VALF, and HUGE_VALL, respectively. If x is NaN, a NaN is returned. If x is +-0, 1.0 is returned. If x is +-Inf, +-Inf is returned. For exceptional cases, matherr(3M) tabulates the values to be returned by cosh() as specified by SVID3 and XPG3. ERRORS
These functions will fail if: Range Error The result would cause an overflow. If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the overflow floating-point exception is raised. The cosh() function sets errno to ERANGE if the result would cause an overflow. USAGE
