Comment (by Mouse <mouse008@…>):
> The example code is wrong (It's been updated in the docs for 1.60).
Here's what I used to guide me:
Boost-1.54 tutorial:
[http://www.boost.org/doc/libs/1_54_0/libs/multiprecision/doc/html/boost_multiprecision/tut/random.html]
Now the Boost-1.60 tutorial:
[http://www.boost.org/doc/libs/1_60_0/libs/multiprecision/doc/html/boost_multiprecision/tut/random.html]
suggests using `cpp_bin_float_50` instead of `mpf_float_50`, and
`independent_bits_engine`. But it is unclear in this example how to
specify a certain number of digits or bits for
`uniform_real_distribution<cpp_bin_float_50>` that uses
`independent_bits_engine<nt19937, ...>`. Perhaps you could point me at a
description/tutorial?
Thanks!
P.S. I tried to replicate the last example from the above 1.60 tutorial,
and here's the result. Am I doing something obviously wrong? This is with
Boost-1.59.
