Function divFloor [src]

q = a / b (rem r) a / b are floored (rounded towards 0). Returns an error if memory could not be allocated.

Prototype

pub fn divFloor(q: *Managed, r: *Managed, a: *const Managed, b: *const Managed) !void

Parameters

q: *Managedr: *Manageda: *const Managedb: *const Managed

Source

  pub fn divFloor(q: *Managed, r: *Managed, a: *const Managed, b: *const Managed) !void {
    try q.ensureCapacity(a.len());
    try r.ensureCapacity(b.len());
    var mq = q.toMutable();
    var mr = r.toMutable();
    const limbs_buffer = try q.allocator.alloc(Limb, calcDivLimbsBufferLen(a.len(), b.len()));
    defer q.allocator.free(limbs_buffer);
    mq.divFloor(&mr, a.toConst(), b.toConst(), limbs_buffer);
    q.setMetadata(mq.positive, mq.len);
