### 1.1

This is SIMD oriented Fast Mersenne Twister(SFMT) pseudorandom number generator. This file provides:

- void init_gen_rand() initializes the generator with a 32-bit integer seed.
- void init_by_array() initializes the generator with an array of 32-bit integers as the seeds.
- inline uint32_t gen_rand32() generates and returns a pseudorandom 32-bit unsigned integer.
- inline uint32_t gen_rand64() generates and returns a pseudorandom 64-bit unsigned integer.
- inline void fill_array32() fills the user-specified array with 32-bit psedorandom integers.
- inline void fill_array64() fills the user-specified array with 64-bit psedorandom integers.
- inline static double to_real1(uint32_t v) convert v to double on [0,1]-real-interval.
- inline static double genrand_real1() generates a random number on [0,1]-real-interval.
- inline static double to_real2(uint32_t v) convert v to double on [0,1)-real-interval.
- inline static double genrand_real2() generates a random number on [0,1)-real-interval.
- inline static double to_real3(uint32_t v) convert v to double on (0,1)-real-interval.
- inline static double genrand_real3() generates a random number on (0,1)-real-interval.
- inline static double to_res53(uint64_t v) convert v to double on [0,1) with 53-bit resolution
- inline static double genrand_res53() generates a random number on [0,1) with 53-bit resolution
