<li>Many methods now use faster algorithms that were not possible to adopt in <code>math/rand</code>
because they changed the output streams.

<li>The
<code>Intn</code>,
<code>Int31</code>,
<code>Int31n</code>,
<code>Int63</code>,
and
<code>Int64n</code>
top-level functions and methods from <code>math/rand</code>
are spelled more idiomatically in <code>math/rand/v2</code>:

pkg math/cmplx, func Tanh(complex128) complex128
pkg math/rand, func ExpFloat64() float64
pkg math/rand, func Float32() float32
pkg math/rand, func Float64() float64
pkg math/rand, func Int() int
pkg math/rand, func Int31() int32
pkg math/rand, func Int31n(int32) int32
pkg math/rand, func Int63() int64
pkg math/rand, func Int63n(int64) int64
