Phi Function - douganc - 07-21-2015 08:39 PM Hello, Can anyone tell me where I am going wrong in this Program? It's purpose is to display the value of Phi to 50 Decimal Places When "phi()" is typed on the home screen. Here is the program: #cas phi():=BEGIN // LOCAL x; x:=(1.61803398874989484820458683436563811772030917980576); RETURN(x); // END; #end Output: See attached Screenshot. Thanks !

after this you won't have that error, but 1.61803398875. then the rest... For "all dec" output see here. Salvo RE: Phi Function - douganc - 07-21-2015 11:28 PM Thank You for Help. Much Appreciated Colm. :-) RE: Phi Function - Gerald H - 07-22-2015 05:24 AM The term "phi function" is already occupied https://en.wikipedia.org/wiki/Euler%27s_totient_function You could amend to "phi constant"? RE: Phi Function - douganc - 07-22-2015 08:58 AM Yes of course, it's a constant not a function. Colm :-) |
