// 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
//

// Define the max and mean errors expected for
// various compilers and platforms.
//
//
// Catch all cases come last:
//

".*", // stdlib
".*", // platform
".*", // test type(s)
".*", // test data group
".*", // test function
4, // Max Peek error
3); // Max mean error
//
// Finish off by printing out the compiler/stdlib/platform names,
// we do this to make it easier to mark up expected error rates.
//

<< BOOST_STDLIB << ", " << BOOST_PLATFORM << std::endl;
