In 1.9, we added bigdec? predicate, but the existing decimal? predicate is the same (this was unintentional).
spec-bigdec.patch - spec.alpha patch to modify spec generator mapping
clj-2259-2.patch - Clojure patch to remove the new bigdec? predicate and update to latest spec (with updated mapping)

Hello, please note that the Cognitect blog article http://blog.cognitect.com/blog/2016/8/9/focus-on-spec-predicates still mentions "bigdec?", which is confusing for people googling for the correct predicate.
I removed it from the blog post.
