@chapter Typedef and constants
The following data type has been defined via @code{typedef}.
@table @asis
@item @code{__complex128}: @code{__float128}-based complex number
@end table
The following macros are defined, which give the numeric limits of the
@code{__float128} data type.
@table @asis
@item @code{FLT128_MAX}: largest finite number
@item @code{FLT128_MIN}: smallest positive number with full precision
@item @code{FLT128_EPSILON}: difference between 1 and the next larger
representable number
@item @code{FLT128_DENORM_MIN}: smallest positive denormalized number
@item @code{FLT128_MANT_DIG}: number of digits in the mantissa (bit precision)
@item @code{FLT128_MIN_EXP}: maximal negative exponent
@item @code{FLT128_MAX_EXP}: maximal positive exponent
@end table
The following mathematical constants of type @code{__float128} are defined.
@table @asis
@item @code{M_Eq}: the constant e (Euler's number)
@item @code{M_LOG2Eq}: binary logarithm of 2
@item @code{M_LOG10Eq}: common, decimal logarithm of 2
@item @code{M_LN2q}: natural logarithm of 2
@item @code{M_LN10q}: natural logarithm of 10
@item @code{M_PIq}: pi
@item @code{M_PI_2q}: two pi
@item @code{M_PI_4q}: four pi
@item @code{M_1_PIq}: one over pi
@item @code{M_2_PIq}: one over two pi
@item @code{M_2_SQRTPIq}: two over square root of pi
@item @code{M_SQRT2q}: square root of 2
@item @code{M_SQRT1_2q}: one over square root of 2
