  19 /* Part of testsuite for libm.
  20
  21    This file is processed by a perl script.  The resulting file has to
  22    be included by a master file that defines:
  23
  24    Macros:
  25    FUNC(function): converts general function name (like cos) to
  26    name with correct suffix (e.g. cosl or cosf)
  27    MATHCONST(x):   like FUNC but for constants (e.g convert 0.0 to 0.0L)
  28    FLOAT:          floating point type to test
  29    - TEST_MSG:     informal message to be displayed
  30    CHOOSE(Clongdouble,Cdouble,Cfloat,Cinlinelongdouble,Cinlinedouble,Cinlinefloat):
  31    chooses one of the parameters as delta for testing
  32    equality
  33    PRINTF_EXPR     Floating point conversion specification to print a variable
  34    of type FLOAT with printf.  PRINTF_EXPR just contains
  35    the specifier, not the percent and width arguments,
  36    e.g. "f".
  37    PRINTF_XEXPR    Like PRINTF_EXPR, but print in hexadecimal format.
  38    PRINTF_NEXPR Like PRINTF_EXPR, but print nice.  */

  40 /* This testsuite has currently tests for:

  59
  60    At the moment the following functions and macros aren't tested:
  61    drem (alias for remainder),
  62    lgamma_r,
  63    nan,
  64    pow10 (alias for exp10).
  65
  66    Parameter handling is primitive in the moment:
  67    --verbose=[0..3] for different levels of output:
  68    0: only error count
  69    1: basic report on failed tests (default)
  70    2: full report on all tests
  71    -v for full output (equals --verbose=3)
  72    -u for generation of an ULPs file
  73  */
  74
  75 /* "Philosophy":
  76
  77    This suite tests some aspects of the correct implementation of
  78    mathematical functions in libm.  Some simple, specific parameters
  79    are tested for correctness but there's no exhaustive
  80    testing.  Handling of specific inputs (e.g. infinity, not-a-number)
  81    is also tested.  Correct handling of exceptions is checked
  82    against.  These implemented tests should check all cases that are
  83    specified in ISO C99.
  84
  85    Exception testing: At the moment only divide-by-zero, invalid,
  86    overflow and underflow exceptions are tested.  Inexact exceptions
  87    aren't checked at the moment.
  88
  89    NaN values: There exist signalling and quiet NaNs.  This implementation
  90    only uses quiet NaN as parameter.  Where the sign of a NaN is
  91    significant, this is not tested.  The payload of NaNs is not examined.
  92
  93    Inline functions: Inlining functions should give an improvement in
  94    speed - but not in precission.  The inlined functions return
  95    reasonable values for a reasonable range of input values.  The
  96    result is not necessarily correct for all values and exceptions are
  97    not correctly raised in all cases.  Problematic input and return
  98    values are infinity, not-a-number and minus zero.  This suite
  99    therefore does not check these specific inputs and the exception
 100    handling for inlined mathematical functions - just the "reasonable"
 101    values are checked.
 102
 103    Beware: The tests might fail for any of the following reasons:
 104    - Tests are wrong
 105    - Functions are wrong
 106    - Floating Point Unit not working properly
 107    - Compiler has errors
 108
 109    With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.
 110
 111
 112    To Do: All parameter should be numbers that can be represented as
 113    exact floating point values.  Currently some values cannot be
 114    represented exactly and therefore the result is not the expected
 115    result.  For this we will use 36 digits so that numbers can be
 116    represented exactly.  */
