... yes if you're an integer maths junkie (and you considered every CPU
cycle was sacred)  you'd probably never have even considered a number range
like -10 +10 you would have gone for -8 +7 or -16 +15 so that you could do a
bit operation like:

random =  ( rand() & 31 ) - 16;    // for -16 +15 range.

.. but who cares :-)

( OK.....I used to care....but I've managed to cure myself of the addiction
now.)
