-- Testcases for functions in cmath. -- -- Each line takes the form: -- -- <testid> <function> <input_value> -> <output_value> <flags> -- -- where: -- -- <testid> is a short name identifying the test, -- -- <function> is the function to be tested (exp, cos, asinh, ...), -- -- <input_value> is a pair of floats separated by whitespace -- representing real and imaginary parts of a complex number, and -- -- <output_value> is the expected (ideal) output value, again -- represented as a pair of floats. -- -- <flags> is a list of the floating-point flags required by C99 -- -- The possible flags are: -- -- divide-by-zero : raised when a finite input gives a -- mathematically infinite result. -- -- overflow : raised when a finite input gives a finite result whose -- real or imaginary part is too large to fit in the usual range -- of an IEEE 754 double. -- -- invalid : raised for invalid inputs. -- -- ignore-real-sign : indicates that the sign of the real part of -- the result is unspecified; if the real part of the result is -- given as inf, then both -inf and inf should be accepted as -- correct. -- -- ignore-imag-sign : indicates that the sign of the imaginary part -- of the result is unspecified. -- -- Flags may appear in any order. -- -- Lines beginning with '--' (like this one) start a comment, and are -- ignored. Blank lines, or lines containing only whitespace, are also -- ignored. -- The majority of the values below were computed with the help of -- version 2.3 of the MPFR library for multiple-precision -- floating-point computations with correct rounding. All output -- values in this file are (modulo yet-to-be-discovered bugs) -- correctly rounded, provided that each input and output decimal -- floating-point value below is interpreted as a representation of -- the corresponding nearest IEEE 754 double-precision value. See the -- MPFR homepage at http://www.mpfr.org for more information about the -- MPFR project. -- A minority of the test cases were generated with the help of -- mpmath 0.19 at 100 bit accuracy (http://mpmath.org) to improve -- coverage of real functions with real-valued arguments. These are -- used in test.test_math.MathTests.test_testfile, as well as in -- test_cmath. -------------------------- -- acos: Inverse cosine -- -------------------------- -- zeros acos0000 acos 0.0
