NAME

llrincw - return uniformly-distributed pseudorandom 64-bit unsigned integer in given range

SYNOPSIS

cc [ flags ] -I/usr/local/include file(s) -L/usr/local/lib -lmcw [ ... ]

#include <mathcw.h>

extern UINT_LEAST64_T llrincw (UINT_LEAST64_T a, UINT_LEAST64_T b);


DESCRIPTION

Compute a pseudorandom 64-bit unsigned integer uniformly distributed in the range [a,b]. The generator state is kept internally to simplify the user interface. However, this is not safe in multithreaded programs. For them, use the reentrant generator routines instead, identified by the suffix _r. The reentrant routines also make possible families of independent generators within the same program.

RETURN VALUES

Return the pseudorandom integer.

ERRORS

If the endpoints are out of order, or their range is too big to represent in a long double, return the first endpoint.
