+ The purpose of Double precision SIMD-oriented Fast Mersenne Twister (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 pseudorandom 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.
