Random Number Generator

This HP-12C program calculates uniformly distributed pseudo-random

numbers

in the range

0 <

< 1.

The following method is used:

• u

+ 1 = fractional part of (997 u

)

•where i = 0, 1, 2, ...

• u

= 0.5284163* (seed), *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.
