We have released Calcish 1.13 with the following changes:

Improved integer log2 precision

Previously, the top-level log2 function returned an inexact big float result for integers perfectly representable as a power of two. For example, log2(2**128) returned 127.99999999999999999999999999999999, even though it should have returned 128. We fixed that.
