question: public static void realWrite ( final OutputStream out , final double [ ] x , final int dp ) throws IOException { out . write ( ( byte ) '[' ) ; for ( int i = 0 ; i < x . length ; i ++ ) { if ( i > 0 ) { out . write ( COMMA_BYTES ) ; } realWrite ( out , x [ i ] , dp ) ; } out . write ( ( byte ) ']' ) ; }
target:  Format a real array in a way that can be easily ported to C#.
