19 /* Part of testsuite for libm.
21 This file is processed by a perl script. The resulting file has to
22 be included by a master file that defines:
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
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,
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:
41 acos, acosh, asin, asinh, atan, atan2, atanh,
42 cbrt, ceil, copysign, cos, cosh, erf, erfc, exp, exp10, exp2, expm1,
43 fabs, fdim, floor, fma, fmax, fmin, fmod, fpclassify,
45 ilogb, isfinite, isinf, isnan, isnormal,
46 isless, islessequal, isgreater, isgreaterequal, islessgreater, isunordered,
48 ldexp, lgamma, log, log10, log1p, log2, logb,
49 modf, nearbyint, nextafter,
50 pow, remainder, remquo, rint, lrint, llrint,
51 round, lround, llround,
52 scalb, scalbn, scalbln, signbit, sin, sincos, sinh, sqrt, tan, tanh, tgamma, trunc,
53 y0, y1, yn, significand
55 and for the following complex math functions:
56 cabs, cacos, cacosh, carg, casin, casinh, catan, catanh,
57 ccos, ccosh, cexp, clog, cpow, cproj, csin, csinh, csqrt, ctan, ctanh.
59 At the moment the following functions aren't tested:
62 Parameter handling is primitive in the moment:
63 --verbose=[0..3] for different levels of output:
65 1: basic report on failed tests (default)
66 2: full report on all tests
67 -v for full output (equals --verbose=3)
68 -u for generation of an ULPs file
73 This suite tests some aspects of the correct implementation of
74 mathematical functions in libm. Some simple, specific parameters
75 are tested for correctness but there's no exhaustive
76 testing. Handling of specific inputs (e.g. infinity, not-a-number)
77 is also tested. Correct handling of exceptions is checked
78 against. These implemented tests should check all cases that are
81 Exception testing: At the moment only divide-by-zero, invalid,
82 overflow and underflow exceptions are tested. Inexact exceptions
83 aren't checked at the moment.
85 NaN values: There exist signalling and quiet NaNs. This implementation
86 only uses quiet NaN as parameter but does not differenciate
87 between the two kinds of NaNs as result.
89 Inline functions: Inlining functions should give an improvement in
90 speed - but not in precission. The inlined functions return
91 reasonable values for a reasonable range of input values. The
92 result is not necessarily correct for all values and exceptions are
93 not correctly raised in all cases. Problematic input and return
94 values are infinity, not-a-number and minus zero. This suite
95 therefore does not check these specific inputs and the exception
96 handling for inlined mathematical functions - just the "reasonable"
99 Beware: The tests might fail for any of the following reasons:
101 - Functions are wrong
102 - Floating Point Unit not working properly
103 - Compiler has errors
105 With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error.
108 To Do: All parameter should be numbers that can be represented as
109 exact floating point values. Currently some values cannot be
110 represented exactly and therefore the result is not the expected
111 result. For this we will use 36 digits so that numbers can be
112 represented exactly. */
