Zmienna `app` będzie tutaj "instancją" klasy `FastAPI`.

Będzie to główny punkt interakcji przy tworzeniu całego interfejsu API.

Ta zmienna `app` jest tą samą zmienną, do której odnosi się `uvicorn` w poleceniu:

<div class="termy">

```console
$ uvicorn main:app --reload

MIN_COMBINED, a small bias is introduced where repeated iterations of quantizing
and dequantizing will introduce a larger and larger error.

*SCALED mode Example*

`SCALED` mode matches the quantization approach used in
`QuantizeAndDequantize{V2|V3}`.

If the mode is `SCALED`, the quantization is performed by multiplying each
input value by a scaling_factor.

always count the number of leading zeros i in the first digit of v and then
shift both u and v left by i bits.

Having scaled u and v, the value ⌊u/v⌋ is unchanged, but the remainder will
be scaled: 172 mod 19 is 1, but 516 mod 57 is 3. We have to divide the remainder
by the scaling factor (shifting right i bits) when we finish.

	//fmt.Printf("testing nsamples=%v mean=%v stddev=%v seed=%v\n", nsamples, mean, stddev, seed);

	samples := generateNormalSamples(nsamples, mean, stddev, seed)
	errorScale := max(1.0, stddev) // Error scales with stddev
	expected := &statsResults{mean, stddev, 0.10 * errorScale, 0.08 * errorScale}

	// Make sure that the entire set matches the expected distribution.
	checkSampleDistribution(t, samples, expected)
