Hi All,

I am trying to calculate Angle by using Degrees(ARCOS) functions in SAS, But Data step getting an errror.Please advice

26 Degrees=DEGREES(ARCOS(Theta/(Len_A+Len_B)));
_______
68
ERROR 68-185: The function DEGREES is unknown, or cannot be accessed.

What version of SAS do you have?

I'm only finding documentation for the function under SAS 9.4 and in PROC FEDSQL. You may need to use a PROC FEDSQL statement to use this function.

The conversion from radians to degrees is fairly straightforward, you should be able to write a basic function or formula if you don't like using FEDSQL.

Define your own function, callable from data steps and SQL:

proc fcmp outlib=sasuser.fcmp.math;
function degrees(radians);
if missing(radians) then return(.);
r = mod(radians, 2*constant("PI"));
return (r*360/(2*constant("PI")));
endsub;
run;

options cmplib=sasuser.fcmp;

data _null_;
do x = -2 to 2 by 0.125;
    r = x*2*constant("PI");
    d = degrees(r);
    put r= d=;
    end;
run;
