Compile-time calculation: Difference between revisions

In both cases, the identifier <code>factorial10</code> is given the value 3628800 without any runtime calculations, although in many (or perhaps most) BASICs the first one is handled similarly to C's <code>#define</code>: if it isn't used elsewhere in the code, it doesn't appear at all in the final executable.

{{omit from|Ruby|Ruby has BEGIN { ... } blocks like Perl, but Ruby runs them at run time, not compile time. The compiler cannot fold constant expressions like 10 * 9, because these call methods like Fixnum#*, and Ruby binds methods at run time. Classes are open; the program might redefine Fixnum#* at run time.}}
