Equivalent to 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. See sprintf
for an explanation of the format argument. 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.
