Type: number, Format: float becomes a double in C#

[martinmolin]

According to https://swagger.io/docs/specification/data-models/data-types/

type	format	Description
number	–	Any numbers.
number	float	Floating-point numbers.
number	double	Floating-point numbers with double precision.
integer	–	Integer numbers.
integer	int32	Signed 32-bit integers (commonly used integer type).
integer	int64	Signed 64-bit integers (long type).

There can be floats as well as doubles, however for the C# generator it seems like both float and double will end up being a double.

Any news?

The problem is that float is not handled here:
https://github.com/RSuter/NJsonSchema/blob/master/src/NJsonSchema/Generation/DefaultReflectionService.cs#L75

And here:
https://github.com/RSuter/NJsonSchema/blob/master/src/NJsonSchema.CodeGeneration.CSharp/CSharpTypeResolver.cs#L140

The format is defined however: https://github.com/RSuter/NJsonSchema/blob/master/src/NJsonSchema/JsonFormatStrings.cs

BTW: Double and float seem to be not defined format types for JSON Schema: https://json-schema.org/latest/json-schema-validation.html#rfc.section.7.3

There's another problem with float and double and its about this types scopes - they can be Infinity or NaN, but generated json schema points them as "number" only.
I think its could be a problem when casting json types onto C# Dto objects.
