The random selection in function linear() could deliver a value equal to max
if geqo_rand() returns exactly 1.0, resulting in failure due to indexing off the end of the pool array. Also, since this is using inexact float math, it seems wise to guard against roundoff error producing values slightly outside the expected range. Per report from bug@zedware.org.
