| The description of the "Format Specification Mini-Language" states for float and Decimal regarding presentation type 'f': "The default precision is 6." Regarding presentation type None it reads: "Similar to 'g', except that fixed-point notation, when used, has at least one digit past the decimal point." While both statements are accurate for float, they don't hold for Decimal. In order to preserve the information about the decimal exponent, in both cases Decimal formatting displays as many fractional digits as dictated by it's exponent. |

| These changes are a big improvement. Thanks, Mark. Should this issue be closed, or are you thinking of more changes? Personally I think we should leave it as it is now, and open another issue if people find fault with the new docs. |

| The 'default precision' issue is addressed; the issues that Michael reported about the `None` presentation type are still valid, I think. |

| > Should this issue be closed, or are you thinking of more changes? I've made one more round of changes in GH-23575. Once that's gone in, I think we can close this issue. I don't think we're ever going to be able to make this table perfectly accurate; at best, we can achieve a series of successive approximations to the truth. (Which is pretty much what I aim for when teaching.) |
