d10 has size 0..9, generally because of size (the print on them is
typically only large enough to have one decimal digit). 0 is rarely a
useful number in gaming, so it is treated as a 10 result. Therefore
rand(10) + 1 is sufficient to represent d10. When used as d100, you'll
get the values 00 .. 99, but again, 00 is not a useful value so it is
treated as 100. So rand(100) + 1 is sufficient to represent d100.
