acosh(3M) acosh(3M) NAME
acosh(), acoshf(), acoshl(), acoshw(), acoshq() - arc hyperbolic cosine functions SYNOPSIS
HP Integrity Server Only DESCRIPTION
returns the arc hyperbolic cosine of x, in the range +zero to +INFINITY. Integrity Server Only is a version of it takes a argument and returns a result. is a version of it takes a argument and returns a result. is an version of it takes an argument and returns an result. is equivalent to on HP-UX systems. USAGE
To use (for Integrity servers) compile either with the default option or with the and options. To use (for Integrity servers) or compile also with the option. To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command line. For more information, see the at the following site: RETURN VALUE
returns +0. If x < 1.0, returns NaN and raises the invalid exception. If x is +INFINITY, returns +INFINITY. If x is NaN, returns NaN. When it raises no other exception, whether raises the inexact exception is unspecified. ERRORS
If x < 1.0, sets to [EDOM]. Integrity Server Only HPUX functions on Integrity servers do not set by default. For setting, compile with the option. SEE ALSO
