acosd(3M)																 acosd(3M)

NAME

       acosd(), acosdf(), acosdl(), acosdw(), acosdq() - degree-valued arccosine functions

SYNOPSIS

   HP Integrity Server Only
DESCRIPTION

       returns the degree-valued arccosine of x, in the range 0 to 180.

       is a version of it takes a argument and returns a result.

   Integrity Server Only
       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 these functions, 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 the magnitude of x is greater than one, returns NaN and raises the invalid exception.

       If x is NaN, returns NaN.

ERRORS

       If the magnitude of x is greater than one, sets to [EDOM].

   Integrity Server Only
       HP-UX libm functions on Integrity server do not set by default.	For setting, compile with the option.
