+/* 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:
+
+ Makros:
+ 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
+
+ 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:
+ conj, cimag, creal, drem,
+ significand,
+ 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 C 9X.
+
+ 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 signalling 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.
