%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 2^521 - 1 to 2^132049 - 1.

dSFMT の開発目的は整数から浮動小数点数への変換のコストを避けることにあります。
dSFMT は IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std
754-1985) 形式の倍精度浮動小数点擬似乱数を直接生成します。 したがって、dSFMT
は IEEE 754 形式の倍精度浮動小数点数を使用する CPU でしか利用出来ません。

dSFMT は整数の出力をサポートしません。
dSFMT がサポートするのは [1, 2), [0, 1), (0, 1], (0, 1) の範囲に分布する
倍精度浮動小数点擬 似乱数です。また、2^521 - 1 から 2^216091 - 1 までの様々な
周期をサポートします。
