In the Details of the document of
RealDigits writes the following line:
RealDigits[x]normally returns a list of digits of length
Then when will
RealDigits[x] abnormally return something and what will be returned?
The details has shown us one of them:
Are there more?
The following is one I found today:
x = 1.2``2; Round@Precision@x (* 2 *) Length@First@RealDigits@x (* 3 *)
Is there a complete summary for the behaviors of
RealDigits with only one valid argument? Does these abnormalities follow any unified rule?
