-- 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.
