Forms Processor Advanced Commands

$output = sprintf("format",variable_list);

• $output - the variable to store the formatted output in.
  
  
• format - a template string to format variable_list to the specified variable.
  
  
• variable_list - a comma separated list of Form Processor variables to use in place of the special template characters in the format string.
  
  
• NOTE:
  The list of special template formatting characters is:
  

  Usage				Char	Range
  -----------------------------------------------------------------
  String				s	32k of data
  Character			c	1 character
  Decimal number			d	-32767 to 32768
  Long decimal number		ld	-2147483647 to 2147483648
  unsigned decimal number		u	0 to 65535
  unsigned long decimal number	lu	0 to 4294967295
  hex number			x	0x0000 to 0xffff
  unsigned long hex number	lx	0x00000000 to 0xffffffff
  octal number			o	0000 to 7777
  long octal number		lo	00000000 to 77777777
  exponential format float number	e	unknown, machine dependent
  floating point number		f	unknown, machine dependent
  compact floating point number	g	unknown
  

  The codes above should be prefixed like so:
  [-]%[n]code
  [-] is optional to left align numbers instead of the default right
  % is to tell that the next part of the string is a format code [n] is the leading number of spaces or template format for numbers, eg:
  %6.2f - would format a floating point number to 6 places before and 2 places after the decimal place; rounding
  code - the special code listed in the table above

Example:

# a not so uncommon large obnoxious number

$large_number = "20590.999999999998";

# round the number off to dollars and cents

$sub_total = sprintf("%6.2f",$large_number);

# now the sub_total contains "$20590.99"

$first_name = "Walt";
$last_name = "Webcom";

# concatenate first and last name is an index format

$name = sprintf("%s, %s",$last_name,$first_name);

# now name is "Webcom, Walt"
# print out the result

Customer index: $name
Your subtotal is: $sub_total
