Perl split sqrt Keywords The sprintf keyword The sprintf function returns a string formatted by the usual printf conventions of the C library function sprintf. If the list is omitted, the contents of $_ is used as format information. To use the printf without a printf, a real filehandler like FH and not an indirect filehandler like $fh is required. In this case, if $_ contains formatting information, it will be replaced by an empty string and a warning will be emitted, if they are enabled. So, it's better to use print when the contents of $_ are to be used as formatting information. print is simpler and less errorprone than printfǃ Syntax sprintf FORMAT, LIST Examples The code $a = 567; while ($a < 1000) { $result = sprintf("%08d", $a); $rounded = sprintf("%.5f", $a); print $result .
