HP41C random number generator help

[Trond]

Just thought I should add to this old thread that the HP-55 statistics book recommends using seed plus Pi to the power of 5 [i.e. (S+π)^5], taking the fraction part of the formula.

The calculator does not have a fraction function, so I find the way they do it a bit interesting: find the whole integer part by doing +1E9 and then -1E9 (essentially letting the calculator cut off the fraction part by squeezing it out of the screen and memory), then subtracting this whole number from the rest.
