What is dSFMT
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.
