[docs] [issue19871] json module won't parse a float that starts with a decimal point

[Ned Batchelder]

Ned Batchelder added the comment:

There are other forms of numbers allowed by Python that are not allowed by JSON: "001.1"

Oddly, with all of the strictness in JSON, the exponent-marker "e" can be upper- or lower-case:  1e1 and 1E1 are both valid JSON.
