Whoa! That's a lot of advice there. Too bad nobody reacted this much to my recent "each2/closure" posting.
I have another solution to contribute for the sake of the mailing list archive:
`{ -40.5 } [ ... >float ] unit-test`
20.01.2017, 16:49, "Jon Harper" <jon.harpe...@gmail.com>:
If you want to see "-40.5" in the unit-test output, then use { t } [ DECIMAL: -41.5 decimal>ratio = ] unit test or { t } [ -41.5 number= ], but comparing floats has precision problems.If you really want to see "-40.5" in the source, you can use the decimals vocab from extra along with the literals vocab:The easy way for approximate equality testing is ~ ( http://docs.factorcode.org/content/word-~,math.functions.html )Also, like björne said, in your case the simplest answer is to use { -40-1/2 } [ ... ] unit-test or { -81/2 } [ ... ] unit test.
${ DECIMAL: -41.5 decimal>ratio }
