in thread sprintf rounding convention

Hmm... Then I think the sprintf documentation is incorrect, or possibly just confusing: (emphasis mine)
Perl does its own "sprintf" formatting--it emulates the C function "sprintf", but it doesn't use it (except for floating- point numbers, and even then only the standard modifiers are allowed). As a result, any non-standard extensions in your local "sprintf" are not available from Perl.

    And what's incorrect about that? Perl prefers the "nearest even round" operation, as I recall, but otherwise should work the same as your local sprintf.
