+ Part of testsuite for libm.
+
+ This 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)
+ MATHTYPE: floating point type to test
+ TEST_MSG: informal message to be displayed
+ CHOOSE(Clongdouble,Cdouble,Cfloat):
+ chooses one of the parameters as epsilon for testing
+ equality
+ PRINTF_EXPR Floating point conversion specification to print a variable
+ of type MATHTYPE with printf. PRINTF_EXPR just contains
+ the specifier, not the percent and width arguments,
+ e.g. "f"
+ */
+
+/* This program isn't finished yet.
+ It has tests for acos, acosh, asin, asinh, atan, atan2, atanh,
+ cbrt, ceil, cos, cosh, exp, exp2, expm1, fabs, floor, fpclassify,
+ frexp, ldexp,
+ log, log10, log1p, log2, logb,
+ pow, sin, sinh, tan, tanh, fabs, hypot.
+ Tests for the other libm-functions will come later.
+
+ The routines using random variables are still under construction. I don't
+ like it the way it's working now and will change it.
+
+ Exception handling has not been implemented so far so don't get fooled
+ that these tests pass.
+
+ 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
+ 2: full report on failed tests
+ 3: full report on failed and passed tests (default)
+ -v for full output (equals --verbose=3)
+ -s,--silent outputs only the error count (equals --verbose=0)
