ACOS
(Function)
Obtains an arc cosine.
ACOS (<Expression>)
This statement obtains the arc cosine of the value in <Expression>.
The obtained value is expressed in degrees and ranges from 0 to 180.
If <Expression> includes a double precision real numeral, the obtained value becomes double precision. Otherwise, a single precision value is obtained.
