Most likely user error. You are asked to provide a coded example to support any behavior that you suspect to be a bug. At the moment the "betting money" (colloquial English for an informed Bayesian prior)  appears to be that you are making a test for numerical equality and don't really understand how to do this properly.

In particular there is no warranty that user errors will be detected.
