-/*							ldrand.c
- *
- *	Pseudorandom number generator
- *
- *
- *
- * SYNOPSIS:
- *
- * double y;
- * int ldrand();
- *
- * ldrand( &y );
- *
- *
- *
- * DESCRIPTION:
- *
- * Yields a random number 1.0 <= y < 2.0.
- *
- * The three-generator congruential algorithm by Brian
- * Wichmann and David Hill (BYTE magazine, March, 1987,
- * pp 127-8) is used.
- *
- * Versions invoked by the different arithmetic compile
- * time options IBMPC, and MIEEE, produce the same sequences.
