名称描述
mpihelp_divremDivide num (NP/NSIZE) by den (DP/DSIZE) and write* the NSIZE-DSIZE least significant quotient limbs at QP* and the DSIZE long remainder at NP. If QEXTRA_LIMBS is* non-zero, generate that many fraction bits and append them after the* other quotient limbs.
mul_n_basecaseMultiply the natural numbers u (pointed to by UP) and v (pointed to by VP),* both with SIZE limbs, and store the result at PRODP. 2 * SIZE limbs are* always stored. Return the most significant limb.* Argument constraints:* 1

mpihelp_mulMultiply the natural numbers u (pointed to by UP, with USIZE limbs)* and v (pointed to by VP, with VSIZE limbs), and store the result at* PRODP. USIZE + VSIZE limbs are always stored, but if the input* operands are normalized
