get_crand
Generate a high-entropy random number from clock time
Syntax
u = get_crand
Arguments
output
u a random number (double)
Description
Generates a 32-bit integer from clock time via an inscrutable munge and converts it to double. (Nearly always) increases sequentially every tenth of a millisecond, and will not repeat for about five days. Handy for initial seeding of RNGs; see rng_seed, startup. On Unix or Mac systems, get_urand is probably to be preferred (for Windows we might implement something based on rand_s at some point).
