Please add this to the documentation of the random() expression:
random(0) uses the variable 0 as a seed value. The memory of variable 0 is
a union of int and double. When used by the expressions ld() and st(),
it's double. When used by random(), then it's int. Important thing to
remember: If you want to set the random generator to a seed value much
different from 0, then you have to use rather big numbers, for example
st(0, 2^41).
