"Random returns a random number larger or equal to 0 and strictly less than L"
However random(a negative number) returns a number <= 0 and > L
program r;
begin
randomize;
writeln('Random(-10) = ',Random(-10));
end.

random(-10) = -1
C:\Users\Bart\LazarusProjecten>test
random(-10) = -4
Maybe my understanding of English ("strictly less than") is not
correct, so I ask here before posting as a bugreport.
My scant knowledge of English leads me to believe that the sentence
should be rephrased in order to cover the negative numbers case:
either:
Random return a random number with the same sign of L, and whose
absolute value is larger or equal to zero and strictly less than the
absolute value of L.
or:
Random return a random number in the range 0 (included) to L (excluded).
Just my 2c.
