## 數值驗證：浮點數、大於與小於 { #number-validations-floats-greater-than-and-less-than }

數值驗證也適用於 `float`。

這時就能看出能宣告 <abbr title="greater than - 大於"><code>gt</code></abbr>（不只是 <abbr title="greater than or equal - 大於或等於"><code>ge</code></abbr>）的重要性。因為你可以要求數值必須大於 `0`，即便它小於 `1`。

所以，`0.5` 是有效的值，但 `0.0` 或 `0` 則無效。

Let's look at how we can make that work.

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.
