// DESCRIPTION:
// ~~~~~~~~~~~~
//
// This file tests the functions log1p and expm1.  The accuracy tests
// use values generated with NTL::RR at 1000-bit precision
// and our generic versions of these functions.
//
// Note that this tests the generic versions of our functions using
// software emulated types.  This ensures these still get tested
// even though we mostly defer to std::expm1 and std::log1p at
// these precisions nowadays
//

      3);                            // Max mean error

   //
