NAMEsinh(), sinhf(), sinhl(), sinhw(), sinhq() — hyperbolic sine functions DESCRIPTIONsinh() returns the hyperbolic sine of x. sinhf() is a float version of sinh(); it takes a float argument and returns a float result. USAGETo use these functions, compile either with the default -Ae option or with the -Aa and -D_HPUX_SOURCE options. To use (for Itanium-based systems) sinhw() or sinhq(), compile also with the -fpwidetypes option. To use any of these functions, make sure your program includes <math.h>, and link in the math library by specifying -lm on the compiler or linker command line. For more information, see the HP-UX Floating-Point Guide. RETURN VALUEsinh(±0) returns ±0. If x is ±INFINITY, sinh() returns ±INFINITY respectively. If x is NaN, sinh() returns NaN. sinh() returns a properly signed infinity (equal to ±HUGE_VAL) in lieu of a value whose magnitude is too large, and raise the overflow and inexact exceptions. When it raises no other exception, whether sinh() raises the inexact exception is unspecified. |
