/* Part of testsuite for libm.

   This file is processed by a perl script.  The resulting file has to
   be included by a master file that defines:

   Macros:
   FUNC(function): converts general function name (like cos) to
   name with correct suffix (e.g. cosl or cosf)
   MATHCONST(x):   like FUNC but for constants (e.g convert 0.0 to 0.0L)
   FLOAT:          floating point type to test
   - TEST_MSG:     informal message to be displayed
   CHOOSE(Clongdouble,Cdouble,Cfloat,Cinlinelongdouble,Cinlinedouble,Cinlinefloat):
   chooses one of the parameters as delta for testing
   equality
   PRINTF_EXPR     Floating point conversion specification to print a variable
   of type FLOAT with printf.  PRINTF_EXPR just contains
   the specifier, not the percent and width arguments,
   e.g. "f".
   PRINTF_XEXPR    Like PRINTF_EXPR, but print in hexadecimal format.
   PRINTF_NEXPR Like PRINTF_EXPR, but print nice.  */

/* This testsuite has currently tests for:
   acos, acosh, asin, asinh, atan, atan2, atanh,
   cbrt, ceil, copysign, cos, cosh, erf, erfc, exp, exp10, exp2, expm1,
   fabs, fdim, floor, fma, fmax, fmin, fmod, fpclassify,
   frexp, gamma, hypot,
   ilogb, isfinite, isinf, isnan, isnormal,
   isless, islessequal, isgreater, isgreaterequal, islessgreater, isunordered,
   j0, j1, jn,
   ldexp, lgamma, log, log10, log1p, log2, logb,
   modf, nearbyint, nextafter,
   pow, remainder, remquo, rint, lrint, llrint,
   round, lround, llround,
   scalb, scalbn, scalbln, signbit, sin, sincos, sinh, sqrt, tan, tanh, tgamma, trunc,
   y0, y1, yn, significand

   and for the following complex math functions:
   cabs, cacos, cacosh, carg, casin, casinh, catan, catanh,
   ccos, ccosh, cexp, clog, cpow, cproj, csin, csinh, csqrt, ctan, ctanh.

   At the moment the following functions aren't tested:
   drem, nan

   Parameter handling is primitive in the moment:
   --verbose=[0..3] for different levels of output:
   0: only error count
   1: basic report on failed tests (default)
   2: full report on all tests
   -v for full output (equals --verbose=3)
   -u for generation of an ULPs file
 */

/* "Philosophy":

   This suite tests some aspects of the correct implementation of
   mathematical functions in libm.  Some simple, specific parameters
   are tested for correctness but there's no exhaustive
   testing.  Handling of specific inputs (e.g. infinity, not-a-number)
   is also tested.  Correct handling of exceptions is checked
   against.  These implemented tests should check all cases that are
   specified in ISO C99.

   Exception testing: At the moment only divide-by-zero and invalid
   exceptions are tested.  Overflow/underflow and inexact exceptions
   aren't checked at the moment.

   NaN values: There exist signalling and quiet NaNs.  This implementation
   only uses quiet NaN as parameter but does not differenciate
   between the two kinds of NaNs as result.

   Inline functions: Inlining functions should give an improvement in
   speed - but not in precission.  The inlined functions return
   reasonable values for a reasonable range of input values.  The
   result is not necessarily correct for all values and exceptions are
   not correctly raised in all cases.  Problematic input and return
   values are infinity, not-a-number and minus zero.  This suite
   therefore does not check these specific inputs and the exception
   handling for inlined mathematical functions - just the "reasonable"
   values are checked.

   Beware: The tests might fail for any of the following reasons:
   - Tests are wrong
   - Functions are wrong
   - Floating Point Unit not working properly
   - Compiler has errors

   With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.


   To Do: All parameter should be numbers that can be represented as
   exact floating point values.  Currently some values cannot be
   represented exactly and therefore the result is not the expected
   result.  For this we will use 36 digits so that numbers can be
   represented exactly.  */
