integerLogBase# :: Integer -> Integer -> Int#


-- | This modules provides access to the <a>Integer</a> constructors and

--   
--   Note that since <tt>integer-gmp</tt> does not depend on <tt>base</tt>,
--   error reporting via exceptions, <tt>error</tt>, or <tt>undefined</tt>
--   is not available. Instead, the low-level functions will crash the

--   
--   Negative exponents are supported if an inverse modulo

--   
--   <b>Warning</b>: It's advised to avoid calling this primitive with

--   failure to do so will likely cause program abortion due to a
--   divide-by-zero fault. See also <a>recipModInteger</a>.
--   
--   Future versions of <tt>integer_gmp</tt> may not support negative

--   
--   Other operations such as <a>quotBigNat</a> may return
