lcong48() void lcong48 ( unsigned short  p[] ) Set up parameters for random number generators (Linear congruential method) Purpose Set up parameters for rand48 series random number generators. Parameters [in] p[]) Array p[7] For linear congruential method Xn+1 = (a*Xn + c) mod m, sets up the multiplicand a and the addend c (m = 2^48). Further, seed value for drand48, lrand48 and mrand48 is initialized.   p[0]〜p[2]: Seed value.   p[3]〜p[5]: Multiplicand a. (default = 25214903917)   p[6]: Addend c. (default = 11) Note This routine is provided for Windows version.
