20 /* Part of testsuite for libm.
22 This file is processed by a perl script. The resulting file has to
23 be included by a master file that defines:
26 FUNC(function): converts general function name (like cos) to
27 name with correct suffix (e.g. cosl or cosf)
28 MATHCONST(x): like FUNC but for constants (e.g convert 0.0 to 0.0L)
29 FLOAT: floating point type to test
30 - TEST_MSG: informal message to be displayed
31 CHOOSE(Clongdouble,Cdouble,Cfloat,Cinlinelongdouble,Cinlinedouble,Cinlinefloat):
32 chooses one of the parameters as delta for testing
34 PRINTF_EXPR Floating point conversion specification to print a variable
35 of type FLOAT with printf. PRINTF_EXPR just contains
36 the specifier, not the percent and width arguments,
38 PRINTF_XEXPR Like PRINTF_EXPR, but print in hexadecimal format.
39 PRINTF_NEXPR Like PRINTF_EXPR, but print nice. */
41 /* This testsuite has currently tests for:
42 acos, acosh, asin, asinh, atan, atan2, atanh,
43 cbrt, ceil, copysign, cos, cosh, erf, erfc, exp, exp10, exp2, expm1,
44 fabs, fdim, floor, fma, fmax, fmin, fmod, fpclassify,
46 ilogb, isfinite, isinf, isnan, isnormal,
47 isless, islessequal, isgreater, isgreaterequal, islessgreater, isunordered,
49 ldexp, lgamma, log, log10, log1p, log2, logb,
50 modf, nearbyint, nextafter,
51 pow, remainder, remquo, rint, lrint, llrint,
52 round, lround, llround,
53 scalb, scalbn, scalbln, signbit, sin, sincos, sinh, sqrt, tan, tanh, tgamma, trunc,
56 and for the following complex math functions:
57 cabs, cacos, cacosh, carg, casin, casinh, catan, catanh,
58 ccos, ccosh, cexp, clog, cpow, cproj, csin, csinh, csqrt, ctan, ctanh.
60 At the moment the following functions aren't tested:
61 drem, significand, nan
63 Parameter handling is primitive in the moment:
64 --verbose=[0..3] for different levels of output:
66 1: basic report on failed tests (default)
67 2: full report on all tests
68 -v for full output (equals --verbose=3)
69 -u for generation of an ULPs file
74 This suite tests some aspects of the correct implementation of
75 mathematical functions in libm. Some simple, specific parameters
76 are tested for correctness but there's no exhaustive
77 testing. Handling of specific inputs (e.g. infinity, not-a-number)
78 is also tested. Correct handling of exceptions is checked
79 against. These implemented tests should check all cases that are
82 Exception testing: At the moment only divide-by-zero and invalid
83 exceptions are tested. Overflow/underflow and inexact exceptions
84 aren't checked at the moment.
86 NaN values: There exist signalling and quiet NaNs. This implementation
87 only uses quiet NaN as parameter but does not differenciate
88 between the two kinds of NaNs as result.
90 Inline functions: Inlining functions should give an improvement in
91 speed - but not in precission. The inlined functions return
92 reasonable values for a reasonable range of input values. The
93 result is not necessarily correct for all values and exceptions are
94 not correctly raised in all cases. Problematic input and return
95 values are infinity, not-a-number and minus zero. This suite
96 therefore does not check these specific inputs and the exception
97 handling for inlined mathematical functions - just the "reasonable"
100 Beware: The tests might fail for any of the following reasons:
102 - Functions are wrong
103 - Floating Point Unit not working properly
104 - Compiler has errors
106 With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.
109 To Do: All parameter should be numbers that can be represented as
110 exact floating point values. Currently some values cannot be
111 represented exactly and therefore the result is not the expected
112 result. For this we will use 36 digits so that numbers can be
113 represented exactly. */
