ACOSD — Arccosine function, degrees#
-
ACOSD(X)#
ACOSD(X)
computes the arccosine ofX
in degrees (inverse ofCOSD(X)
).- Parameters
X – The type shall either be
REAL
with a magnitude that is less than or equal to one - or the type shall beCOMPLEX
.- Returns
The return value is of the same type and kind as
X
. The real part of the result is in degrees and lies in the range 0 leq Re acos(x) leq 180.
