The following data type has been defined via typedef.
__complex128: __float128-based complex numberThe following macros are defined, which give the numeric limits of the
__float128 data type.
FLT128_MAX: largest finite numberFLT128_MIN: smallest positive number with full precisionFLT128_EPSILON: difference between 1 and the next largerrepresentable number
FLT128_DENORM_MIN: smallest positive denormalized numberFLT128_MANT_DIG: number of digits in the mantissa (bit precision)FLT128_MIN_EXP: maximal negative exponentFLT128_MAX_EXP: maximal positive exponentFLT128_DIG: number of decimal digits in the mantissaFLT128_MIN_10_EXP: maximal negative decimal exponentFLT128_MAX_10_EXP: maximal positive decimal exponentThe following mathematical constants of type __float128 are defined.
M_Eq: the constant e (Euler’s number)M_LOG2Eq: binary logarithm of 2M_LOG10Eq: common, decimal logarithm of 2M_LN2q: natural logarithm of 2M_LN10q: natural logarithm of 10M_PIq: piM_PI_2q: pi divided by twoM_PI_4q: pi divided by fourM_1_PIq: one over piM_2_PIq: one over two piM_2_SQRTPIq: two over square root of piM_SQRT2q: square root of 2M_SQRT1_2q: one over square root of 2
