+
+// this program is a JavaScript version of Mersenne Twister, with concealment and encapsulation in class,
+// an almost straight conversion from the original program, mt19937ar.c,
+// translated by y. okada on July 17, 2006.
+// Changes by Jesse Ruderman: added "var" keyword in a few spots; added export_mta etc; pasted into fuzz.js.
+// in this program, procedure descriptions and comments of original source code were not removed.
+// lines commented with //c// were originally descriptions of c procedure. and a few following lines are appropriate JavaScript descriptions.
+// lines commented with /* and */ are original comments.
+// lines commented with // are additional comments in this JavaScript version.
+// before using this version, create at least one instance of MersenneTwister19937 class, and initialize the each state, given below in c comments, of all the instances.
+/*
+ A C-program for MT19937, with initialization improved 2002/1/26.
+ Coded by Takuji Nishimura and Makoto Matsumoto.
+
+ Before using, initialize the state by using init_genrand(seed)
+ or init_by_array(init_key, key_length).
