Caller
NameDescribe
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
mpih_sqr_n_basecase
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
