[erlang-questions] On OTP rand module difference between OTP 19 and OTP 20

[Richard A. O'Keefe]

For what it's worth, here is an extract from the R documentation.

runif(n, min = 0, max = 1)       # min and max have defaults
...
'runif' will not generate either of the extreme values unless
'max = min' or 'max-min' is small compared to 'min',
and in particular not for the default arguments.
