print FILEHANDLE sprintf(FORMAT, LIST), except that
$\ (the output record separator) is not appended. The first argument of the list will be interpreted as the
printf() format. If
use locale is in effect, the character used for the decimal point in formatted real numbers is affected by the LC_NUMERIC locale. See perllocale.
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.
