## Re: degrees() and acos() functions in SAS DataStep

Hi @Coa_SAs,

I think there is no DEGREES function available in the data step (as opposed to FedSQL), but who would really need a function that multiplies its argument by a constant?

The ACOS function is named ARCOS in the data step.

So, in a data step the calculation could be done as follows:

``````data _null_;
c=sqrt(.5); /* example */
a=180*arcos(c)/constant('pi');
put a;
run; /* result: 45 */``````

## Re: degrees() and acos() functions in SAS DataStep

You say SAS data step but then FEDSQL, which one are you looking to do?

I'm assuming the function, as is, is not working in someway?
