    Test Identification Base/acosh 5
    Problem Summary PG4U.00013 The request is refused because it does not demonstrate a test failure.
    Problem Text
    The CASPEC man page for acosh() states that errno MAY be set to EDOM if
    NaN is passed in. This test erroneously fails because it assumes that
    EDOM will always be set if NaN is passed in.

    The following tests also fail for the same reason:

    asinh() Test 3
    atanh() Test 3
    cbrt() Test 3
    expm1() Test 7
    logb() Test 6
    nextafter() Test 6, 7
    remainder() Test 9, 10
    rint() Test 7
    Test Output
    TEST CASE: acosh

    TEST PURPOSE #5
    If the implementation supports NaN:
    EDOM in errno on a call to double acosh(double x) when
    x is NaN.
    PREP: Check for NaN support
    TEST: acosh(NaN) places EDOM in errno
    WARNING: acosh set errno to 0(0 - No error)
    5 WARNING

    TEST CASE: asinh

    TEST PURPOSE #3
    If the implementation supports NaN:
    EDOM in errno a call to double asinh(double x) when x
    is NaN.
    PREP: Check for NaN support
    TEST: asinh(NaN) places EDOM in errno
    WARNING: asinh set errno to 0(0 - No error)
    3 WARNING

    TEST CASE: atanh

    TEST PURPOSE #3
    If the implementation supports NaN:
    EDOM in errno on a call to double atanh(double x) when
    x is NaN.
    PREP: Check for NaN support
    TEST: atanh(NaN) places EDOM in errno
    WARNING: atanh set errno to 0(0 - No error)
    3 WARNING

    TEST CASE: cbrt

    TEST PURPOSE #3
    If the implementation supports NaN:
    EDOM in errno on a call to double cbrt(double x) when
    x is NaN.
    PREP: Check for NaN support
    TEST: EDOM in errno
    WARNING: cbrt set errno to 0(0 - No error)
    3 WARNING

    TEST CASE: expm1

    TEST PURPOSE #7
    If the implementation supports NaN:
    EDOM in errno on a call to double expm1(double x) when
    x is NaN.
    PREP: Check for NaN support
    TEST: expm1(NaN) places EDOM in errno
    WARNING: expm1 set errno to 0(0 - No error)
    7 WARNING

    TEST CASE: logb

    TEST PURPOSE #6
    If the implementation supports NaN:
    EDOM in errno on a call to double logb(double x) when
    x is NaN.
    PREP: Check for NaN support
    TEST: logb(NaN) places EDOM in errno
    WARNING: logb set errno to 0(0 - No error)
    6 WARNING

    TEST CASE: nextafter

    TEST PURPOSE #6
    If the implementation supports NaN:
    EDOM in errno on a call to double nextafter(double x,
    double y) when x is NaN.
    PREP: Check for NaN support
    TEST: EDOM in errno
    WARNING: nextafter set errno to 0(0 - No error)
    6 WARNING

    TEST PURPOSE #7
    If the implementation supports NaN:
    EDOM in errno on a call to double nextafter(double x,
    double y) when y is NaN.
    PREP: Check for NaN support
    TEST: EDOM in errno
    WARNING: nextafter set errno to 0(0 - No error)
    7 WARNING

    TEST CASE: remainder

    TEST PURPOSE #9
    If the implementation supports NaN:
    EDOM in errno on a call to double remainder(double x,
    double y) when x is NaN.
    PREP: Check for NaN support
    TEST: remainder(NaN, y) places EDOM in errno
    WARNING: remainder set errno to 0(0 - No error)
    9 WARNING

    TEST PURPOSE #10
    If the implementation supports NaN:
    EDOM in errno on a call to double remainder(double x,
    double y) when y is NaN.
    PREP: Check for NaN support
    TEST: remainder(x, NaN) places EDOM in errno
    WARNING: remainder set errno to 0(0 - No error)
    10 WARNING

    TEST CASE: rint

    TEST PURPOSE #7
    If the implementation supports NaN:
    EDOM in errno on a call to double rint(double x) when
    x is NaN.
    PREP: Check for NaN support
    TEST: rint() returns correct value
    WARNING: rint set errno to 0(0 - No error)
    7 WARNING
