To reproduce:
1. Open attached Unity project "randomvalue.zip"
2. Open "doesnotreturn" scene
3. Go into Play mode

Expected result: By description, Random.value should include values from 0.0f to 1.0f [inclusive] , which means it should be possible to get 0.0f and 1.0f as a Random.value,
Actual result: it is impossible to get either of these values in any version of Unity.

Note: I attached a project which has a script. In that script I have made a loop that is generating random.value until it reaches either 0.0f or 1.0f.
pressing Play freezes Unity, which means that the loop is infinite which means Random.value never gets a value of 0.0f or 1.0f.
