4.1 Nomenclature and Types

Complex number or Complex for short, is a pair of two arbitrary precision floating-point numbers (for the real and imaginary parts). The C data type for such objects is mpc_t.

The Precision is the number of bits used to represent the mantissa of the real and imaginary parts; the corresponding C data type is mpfr_prec_t. For more details on the allowed precision range, see Section “Nomenclature and Types” in MPFR.

The rounding mode specifies the way to round the result of a complex operation, in case the exact result can not be represented exactly in the destination mantissa; the corresponding C data type is mpc_rnd_t. A complex rounding mode is a pair of two rounding modes: one for the real part, one for the imaginary part.
