Numeric or string format?

This listing seems to be zero-padded, but surely that is only for presentation and not the case for the actual data format? I came across this to resolve an argument between coworkers who have implemented this as a string "because it has leading zeroes". JanGB (talk) 12:12, 7 September 2020 (UTC)[reply]

The value is a number. It's represented in the standard (as represented by e.g. [1] at least) with leading zeros, so this article follows suit. Your coworker may want to review printf format strings, it's the difference between %d and d. Anomie ⚔ 12:44, 7 September 2020 (UTC)[reply]

Quick response! Still, even reading this page does not make it very clear that the leading zeroes are safe to discard. JanGB (talk) 12:49, 7 September 2020 (UTC)[reply]
