Thanks for the quick reply! Well primarily I don't get the point of the existence of the BD g/G suffix at all. So that it works, the number before needs to contain . or e; but if so, the number is a BD anyway even without the suffix. Is there any case where the g/G BD suffix wouldn't be completely superfluous and adding/removing it would change the code behaviour in the slightest?
Aside of that, there is a very minute and completely unimportant limitation that when I happen to need a BD constant whose value happens to be integral (eg., 1 or 666), there is (far as I know) no way to express it with a suffix in a format 1x, 666x (where x would be the suffix). That's somewhat inconsistent with other cases, e.g., 1f, 666f when the type I happen to need is a float. Nevertheless of course adding “.0” to get a BD is trivial and works reliably, thus it's really just a question of consistency, nothing else :) Thanks and all the best, OC > On 20. 8. 2025, at 3:46, Paul King <pa...@asert.com.au> wrote: > > 1g or 1G gives a BigInteger and here the suffix is required to not get an > Integer.
