GNU Info (g77-300.info)Rand IntrinsicRand Intrinsic .............. Rand(FLAG) Rand: `REAL(KIND=1)' function. FLAG: `INTEGER'; OPTIONAL; scalar; INTENT(IN). Intrinsic groups: `unix'. Description: Returns a uniform quasi-random number between 0 and 1. If FLAG is 0, the next number in sequence is returned; if FLAG is 1, the generator is restarted by calling `srand(0)'; if FLAG has any other value, it is used as a new seed with `srand'. Note: SRand Intrinsic. _Note:_ As typically implemented (by the routine of the same name in the C library), this random number generator is a very poor one, though the BSD and GNU libraries provide a much better implementation than the `traditional' one. On a different system you almost certainly want to use something better. automatically generated by info2www version 1.2.2.9 |
