optimizations. Setting the variable to 0 or unsetting it will
            disable the optimizations.
        *   These optimizations can yield slightly different numerical results
            from when they are off due to floating-point round-off errors from
            different computation approaches and orders.
        *   To verify that the optimizations are on, look for a message with

b.l1 v.l2 = a.l2 + b.l2 v.l3 = a.l3 + b.l3 v.l4 = a.l4 + b.l4 // Using the generic implementation here is actually faster than the // assembly. Probably because the body of this function is so simple that // the compiler can figure out better optimizations by inlining the carry // propagation. return v.carryPropagateGeneri() } // Subtract sets v = a - b, and returns v. func (v *Element) Subtract(a, b *Element) *Element { // We first add 2 * p, to guarantee the subtraction won't underflow, and //...

uint128, a, b uint64) uint128 { hi, lo := bits.Mul64(a, b) lo, c := bits.Add64(lo, v.lo, 0) hi, _ = bits.Add64(hi, v.hi, c) return uint128{lo, hi} } // mul19 returns v * 19. func mul19(v uint64) uint64 { // Using this approach seems to yield better optimizations than *19. return v + (v+v<<3)<<1 } // addMul19 returns v + 19 * a * b, where a and b are at most 52 bits. func addMul19(v uint128, a, b uint64) uint128 { hi, lo := bits.Mul64(mul19(a), b) lo, c := bits.Add64(lo, v.lo, 0) hi, _ = bits.Add64(hi,...

* ♻ Remove `media_type` from `ORJSONResponse` as it's inherited from the parent class. PR [#5805](https://github.com/tiangolo/fastapi/pull/5805) by [@Kludex](https://github.com/Kludex).
* ♻ Instantiate `HTTPException` only when needed, optimization refactor. PR [#5356](https://github.com/tiangolo/fastapi/pull/5356) by [@pawamoy](https://github.com/pawamoy).
