The result of
(random -20 -10)is a negative number. See also racket/racket#4562I'm not sure that I'm using the correct types, because I never remember which is
fixnum?, which one isexact-integer?and which one includes fake integers like7.0.The next line should be fixed too,
because the maximal number
4294967086is not a fixnum in 32 bits.I tried to add a test with negatives, but I get an error that I don't understand.
