  "message": "math/rand: restore Go 1.2 value stream for Float32, Float64\n\nCL 22730043 fixed a bug in these functions: they could\nreturn 1.0 despite documentation saying otherwise.\nBut the fix changed the values returned in the non-buggy case too,\nwhich might invalidate programs depending on a particular\nstream when using rand.Seed(0) or when passing their own\nSource to rand.New.\n\nThe example test says:\n        // These tests serve as an example but also make sure we don\u0027t change\n        // the output of the random number generator when given a fixed seed.\nso I think there is some justification for thinking we have\npromised not to change the values. In any case, there\u0027s no point in\nchanging the values gratuitously: we can easily fix this bug without\nchanging the values, and so we should.\n\nThat CL just changed the test values too, which defeats the\nstated purpose, but it was just a comment.\nAdd an explicit regression test, which might be\na clearer signal next time that we don\u0027t want to change\nthe values.\n\nFixes #6721. (again)\nFixes #8013.\n\nLGTM\u003dr\nR\u003diant, r\nCC\u003dgolang-codereviews\nhttps://golang.org/cl/95460049\n",
