Random Number Generator
This HP-12C program calculates uniformly distributed pseudo-random numbers
u
i
in the range
0 < u
i
< 1.
The following method is used:
•
u
i
+ 1 = fractional part of (997 u
i
)
•
where i = 0, 1, 2, ...
•
u

Other seeds may be selected but the quotient of (seed x 10

)
divided by two or five must not be an integer. Also, it would be wise to statistically test
other seeds before using them. )
The period of this generator has a length of 500,000 numbers and the generator
passes the frequency test (chi Square) for uniformity, the serial test and the run
test. The most significant digits (the left hand digits) are the most random digits.
The right most digits are significantly less random.
