acosd(3M)acosd(3M)NAMEacosd(), acosdf(), acosdl(), acosdw(), acosdq() - degree-valued arcco‐
sine 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.
