    Encodes a Decimal as int if there's no exponent, otherwise float

    This is useful when we use ConstrainedDecimal to represent Numeric(x,0)
    where an integer (but not int typed) is used. Encoding this as a float
    results in failed round-tripping between encode and parse.
    Our Id type is a prime example of this.

# Ek Veri Tipleri { #extra-data-types }

Şimdiye kadar şunlar gibi yaygın veri tiplerini kullanıyordunuz:

* `int`
* `float`
* `str`
* `bool`

Ancak daha karmaşık veri tiplerini de kullanabilirsiniz.

Ve yine, şimdiye kadar gördüğünüz özelliklerin aynısına sahip olursunuz:

* Harika editör desteği.
* Gelen request'lerden veri dönüştürme.
* response verileri için veri dönüştürme.
* Veri doğrulama.
