Sure, but realize also that this is not specific to Julia. The same floating-point standard is followed by essentially all modern languages, and there is lots of learning material online about this (including in Julia).

(Whether `big` prints all of the digits, i.e. an exact decimal representation, depends on the current precision setting, since `BigFloat` is variable precision. I don’t remember off the top of my head if there is a function that always prints the exact decimal representation of a floating-point value, regardless of the precision and regardless of how many decimal digits are required?)
