The following six PRECision parameters are predefined with respect to the IEEE-754 standard (see References), except notably for the meaningless precision:
MPRI_PREC_BITS_NIL: meaningless precision,
MPRI_PREC_BITS_HALF: half precision (binary16) or 11 bits,
MPRI_PREC_BITS_SINGLE: single precision (binary32) or 24 bits,
MPRI_PREC_BITS_DOUBLE: double precision (binary64) or 53 bits,
MPRI_PREC_BITS_QUADRUPLE: quadruple precision (binary128) or 113 bits,
MPRI_PREC_BITS_OCTUPLE: octuple precision or 237 bits.
The following three SuRrouNDing modes are supported:
MPRI_SRND_BCAL: Best Convert At Left endpoint,
MPRI_SRND_BCAA: Best Convert At Any endpoint,
MPRI_SRND_BCAR: Best Convert At Right endpoint.
