Re^3: sprintf percent formatting by tphyahoo (Vicar) on Aug 17, 2005 at 13:14 UTC
No no, I was happy with all three answers about dropping the 0. In fact, it was a testing situation that led me to post this question, but I am okay with my current Test::More solution, which winds up along the lines of `......code..... ok($keyword_density >= $min_keyword_density,"Keyword density " . sprin +tf("%2d%%",$keyword_density100) . ", minimum " . sprintf("%2d%%",$mi +n_keyword_density100) );` [download] This seems elegant enough for me, but as always I welcome suggestions.	[reply] [d/l]

As requested, a non-sprintf solution: `$percent = int(100 * $one_thirtieth) . '%';` Think about what rounding behavior you need; if $f = 888/1000, then: int`(100$f)` will truncate to 88, sprintf`( '%d',100$f)` will truncate to 88, sprintf`('%.0f',100$f)` will round to 89. You can merge formatting and concatenations into a single sprintf call: `ok( $keyword_density >= $min_keyword_density, sprintf( 'Keyword density %.0f%%, minimum %.0f%%', 100 $keyword_density, 100 * $min_keyword_density, ) );` [download] Here is the code I was testing with: Read more...
