/* mpn_divrem_1(quot_ptr, qsize, dividend_ptr, dividend_size, divisor_limb) --
|
|
Divide (DIVIDEND_PTR,,DIVIDEND_SIZE) by DIVISOR_LIMB.
|
|
Write DIVIDEND_SIZE limbs of quotient at QUOT_PTR.
|
|
Return the single-limb remainder.
|
|
There are no constraints on the value of the divisor.
|
|
|
|
QUOT_PTR and DIVIDEND_PTR might point to the same limb.
