If I change maximum: 1e2 to maximum: 100, it validates without error.

Hi @redparham

you use OpenAPI 3.0.3 (Wright Draft 00 schema) which doesn't support integers as floats. Switch to OpenAPI 3.1 (Draft 2020-12 schema) and it should work for you.

Hi @p1c2u.

I see this in the 3.0.1 and 3.1.0 spec:

Note that integer as a type is also supported and is defined as a JSON number without a fraction or exponent part. https://spec.openapis.org/oas/v3.1.0#data-types

[p1c2u]

Hmm , that's true. I will investigate this more.
