From the documentation (emphasis mine):

Preceding the width field by a zero ('0') character enables sign-aware zero-padding for numeric types. It forces the padding to be placed after the sign or base (if any) but before the digits. This is used for printing fields in the form ‘+000000120’. This option is only valid for numeric types and it has no effect on formatting of infinity and NaN.

fmt::print("'{:+06}'\n", NAN);
// output: '00+nan'
