printf [filehandle]format,list

Prints a
formatted string of the elements in *list* to
*filehandle* or, if omitted, the
currently selected output filehandle. This
is similar to the C library's `printf`

and
`fprintf`

functions, except that the
`*`

field width specifier is not supported. The function is
exactly equivalent to:

filehandlesprintf(format,list);

`printf`

and `sprintf`

use the same format syntax, but
`sprintf`

only returns a string; it doesn't print to a
filehandle. The A percent sign begins each field, and%m.nx

*x*

is the type of field.
The optional *m*

gives the minimum field width for appropriate
field types (negative *m*

left-justifies).
The *.n*

gives the precision for a specific
field type, such as the number of digits after a decimal point for floating-point
numbers,
the maximum length for a string, and the minimum length for an integer.Field specifiers (

) may be the following:
*x*
