// DESCRIPTION:
// ~~~~~~~~~~~~
//
// This file tests the functions log1p and expm1 for
// simple multiprecision types which are able to utilize
// our own rational approximations. This tests those
// approximations even when float/double/long double
// are not using them.
//

// 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.
