/* We need the long double type to be IBM 128-bit because the CONVERT_TO_PINF
tests will fail if we use IEEE 128-bit floating point. This is due to IEEE
128-bit having a larger exponent range than IBM 128-bit extended double. So
tests that would generate an infinity with IBM 128-bit will generate a
normal number with IEEE 128-bit. */
