printf FORMAT, LIST
print FILEHANDLE sprintf(FORMAT, LIST). The first argument of the list will be interpreted as the printf format. If
use localeis in effect, the character used for the decimal point in formatted real numbers is affected by the LC_NUMERIC locale. See the perllocale manpage.
Don't fall into the trap of using a
printf() when a simple
print() would do. The
print() is more efficient,
and less error prone.
