Leading zeroes #266
Description
Activity
Seems reasonable to me. Reprex:
collectorGuess("00001", default_locale())Hmmm, this is easy enough to do for integers, but what's the rule for doubles? Should
001.1234be parsed as a double? What about0.1? Is the rule that if there's an initial zero, it must be followed by a period?I think if it just worked for integers that would still be really nice. All my real-life examples are unambiguously integer (last x digits of student IDs, player numbers such as
00or06, etc.).You have to think about doubles because
00001is both an integer and a double, so if I fix it so readr doesn't think it's an integer, it'll just get detected as a double, which isn't a big improvement.This is what I have so far
collector_guess("0") #> [1] "integer" collector_guess("0.") #> [1] "double" collector_guess("0001") #> [1] "character"

I wonder if leading zeroes should cause a column to come in as character? I know I can force the variable to be character and will do so in my current example.
But I suspect that numbers with leading zeroes should be treated as character more often than not. Examples: social security numbers, zip codes, phone numbers with country exit codes, numbers written written for alphalexical sorting, and agent identifiers in the 00 Section of MI6.
