Wrong/ missing values for numeric examples

[chmerk]

I found two funny bugs in the generated examples, possibly related:

1. When using a numeric value with fractional digits, some digits are appended or the number gets "rounded" in a weird way. Example: "price": 12.3, produces

   "price": {
     "$id": "/properties/price",
     "type": "number",
     "title": "The Price Schema ",
     "default": 0,
     "examples": [
       12.300000190734863
     ]
   },

   or "Y": 9.386496 produces..."examples": [ 9.386495590209961 ]

2. The "example generator" also seems to have an issue with the numbers "4" and "5" in numeric arrays: "storage": [2,13,5,42] produces "examples": [ 2, 13, 42 ]

or to exaggerate this:

"numArray": [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 ] produces ... "examples": [ 0, 1, 2, 3, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 ] // 4 and 5 are missing!

Thanks for taking the time to report this Chris. I know it takes time and effort, so it is appreciated.

1. You're the first person to report this, so thank you for being diligent. In return, I spent my evening looking into it. It's down to the way Python's json package formats floats. I've monkey-patched the json package for now, so this will be fixed in the next release. The monkey-patch will likely remain in place until the service is rewritten in Go later this year.

2. This was actually fixed a while back - but I've rolled far too many updates into the forthcoming release, so it got pushed-out. Should be with you less than a week.

Regarding 1. { "price": 12.3 } now generates:

"price": {
      "$id": "#/properties/price", 
      "type": "number", 
      "title": "The Price Schema", 
      "default": 0.0, 
      "examples": [
        12.3
      ]
    }

Regarding 2. "storage": [2,13,5,42] now generates:

"storage": {
      "$id": "#/properties/storage", 
      "type": "array", 
      "title": "The Storage Schema", 
      "items": {
        "$id": "#/properties/storage/items", 
        "type": "integer", 
        "title": "The Items Schema", 
        "default": 0, 
        "examples": [
          2, 
          13, 
          5, 
          42
        ]
      }
    }
