Double precision SIMD-oriented Fast Mersenne Twister
Description
The purpose of dSFMT is to speed up the generation by avoiding
the expensive conversion of integer to double (floating point).
dSFMT directly generates double precision floating point
pseudo-random numbers which have the IEEE Standard for Binary
Floating-Point Arithmetic (ANSI/IEEE Std 754-1985) format.
dSFMT is only available on the CPUs which use IEEE 754 format
double precision floating point numbers.
dSFMT doesn't support integer outputs.
dSFMT supports the output of double precision floating point
pseudo-random numbers which distribute in the range of
[1, 2), [0, 1), (0, 1] and (0, 1).
And it also supports the various periods form 2607-1 to 2132049-1.
