Decimals represented in scientific notation cannot be rendered in YAML rendered

[mdefeche]

Describe the bug
Renderer cannot represent numbers written in scientific notation.

To Reproduce
Use a validator using decimal.Decimal with a least 7 decimals. Starting at 7 decimals, numbers will get printed in scientific notation (eg. 1E-7)

class MyTestModel(models.Model):

    value= models.DecimalField(
        max_digits=9
        decimal_places=7,
        validators=[MinValueValidator(Decimal("0.0000001")), MaxValueValidator(Decimal("1.0"))],
    )

The resulting YAML will look like !!int '1E-7' and an error will be generated in Redoc view cannot resolve a node with !<tag:yaml.org,2002:int> explicit tag

Expected behavior
The value should be 0.0000001 in the yaml file.

It looks like the issue comes from the following method where the str method is used. Maybe a format would work value = '{:f}'.format(data)

Thank you in advance

I confirm the fix is working as expected

        value:
          type: number
          format: double
          maximum: 1.0
          minimum: 0.0000001

Thank you for swiftly fixing this
