sinh, sinhf, sinhl - hyperbolic sine function SYNOPSIS
cc [ 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
