tuple_acos

Herror ::tuple_acos ( const HTuple &T, double *ACos ) Herror ::tuple_acos ( const HTuple &T, HTuple *ACos )

Compute the arccosine of a tuple.

::tuple_acos computes the arccosine of the input tuple T. The arccosine is always returned as a floating point number. The arccosine of a string is not allowed.

Parameters

`T` (input_control)	number(-array) `->` HTuple.double / long
Input tuple.
Restriction: `(-1 <= T) <= 1`

`ACos` (output_control)	number(-array) `->` (HTuple.) double *
Arccosine of the input tuple.

Alternatives

::tuple_asin, ::tuple_atan, ::tuple_atan2
