/* 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. */
