14:17 aditsu is there a DecimalFormat that behaves like Double.toString?
14:44 df0_ joined ##friendlyjava
15:27 pdurbin How does it behave? I should upgrade to Java 9 so I can have a REPL.
17:07 aditsu pdurbin: e.g. 1 -> "1.0", 1e50 -> "1.0e50"
17:10 aditsu scala has a REPL
17:12 aditsu pdurbin: there's also http://www.javarepl.com
17:16 pdurbin "###.##" according to https://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html I guess. "123456.79" as output
17:18 aditsu "###.##" gives "1" and "10000000000000000000000000​0000000000000000000000000"
17:18 aditsu just like toString.. except totally different :p
17:19 aditsu also, 123456.789 is supposed to come out as "123456.789"
17:23 pdurbin hmm, if you figure it out, please let us know
17:23 aditsu so far, it looks like it doesn't exist, which is weird and sucks
17:24 pdurbin time to ask on Stack Overflow, I guess
17:25 aditsu oh yeah, I forgot about that..

17:42 aditsu posted: https://stackoverflow.com/questions/47251895/is-there-a-decimalformat-that-behaves-like-double-tostring
17:53 pdurbin looks good
17:54 * pdurbin votes it up
18:53 pdurbin aditsu: is it using `FloatingDecimal.toJavaFormatString`? See http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/d5a00b1e8f78/src/share/classes/java/lang/Double.java#l203
18:55 aditsu you mean toString? yes, that's internal implementation details..
18:55 aditsu not part of the public API
18:56 pdurbin sure, but it would give you what you want, I would think
18:57 aditsu if it had a format pattern, maybe
18:59 pdurbin yeah, that's what I was hoping I'd find inside. no such luck
19:37 df0_ joined ##friendlyjava
20:53 aditsu I answered my own question..
22:38 kirua joined ##friendlyjava
22:40 pdurbin Cool. Pretty complex answer. I guess you should accept your own answer, if you can.
