NAME ^

Template::Plugin::Number::Format - Plugin/filter interface to Number::Format

SYNOPSIS ^

    [% USE Number.Format %]
    [% num | format_number %]

ABSTRACT ^

Template::Plugin::Number::Format makes the number-munging grooviness of Number::Format available to your templates. It is used like a plugin, but installs filters into the current context.

DESCRIPTION ^

All filters created by Template::Plugin::Number::Format can be configured by constructor options and options that can be passed to individual filters. See "METHODS" in Number::Format for all the details.

Constructor Parameters

The USE line accepts the following parameters, all optional, which define the default behavior for filters within the current Context:

THOUSANDS_SEP

character inserted between groups of 3 digits

DECIMAL_POINT

character separating integer and fractional parts

MON_THOUSANDS_SEP

like THOUSANDS_SEP, but used for format_price

MON_DECIMAL_POINT

like DECIMAL_POINT, but used for format_price

INT_CURR_SYMBOL

character(s) denoting currency (see format_price())

DECIMAL_DIGITS

number of digits to the right of dec point (def 2)

DECIMAL_FILL

boolean; whether to add zeroes to fill out decimal

NEG_FORMAT

format to display negative numbers (def -x)

KILO_SUFFIX

suffix to add when format_bytes formats kilobytes

MEGA_SUFFIX

suffix to add when format_bytes formats megabytes

GIGA_SUFFIX

suffix to add when format_bytes formats gigabytes

Using Template::Plugin::Number::Format ^

When you invoke:

    [% USE Number.Format(option = value) %]

the following filters are installed into the current Context:

round($precision)

Rounds the number to the specified precision. If "$precision" is omitted, the value of the "DECIMAL_DIGITS" parameter is used (default value 2).

format_number($precision, $trailing_zeros)

Formats a number by adding "THOUSANDS_SEP" between each set of 3 digits to the left of the decimal point, substituting "DECIMAL_POINT" for the decimal point, and rounding to the specified precision using "round()". Note that "$precision" is a maximum precision specifier; trailing zeroes will only appear in the output if "$trailing_zeroes" is provided, or the parameter "DECIMAL_FILL" is set, with a value that is true (not zero, undef, or the empty string). If "$precision" is omitted, the value of the "DECIMAL_DIGITS" parameter (default value of 2) is used.

format_negative($picture)

Formats a negative number. Picture should be a string that contains the letter "x" where the number should be inserted. For example, for standard negative numbers you might use "-x", while for accounting purposes you might use "(x)". If the specified number begins with a - character, that will be removed before formatting, but formatting will occur whether or not the number is negative.

format_picture($picture)

Returns a string based on "$picture" with the "#" characters replaced by digits from "$number". If the length of the integer part of $number is too large to fit, the "#" characters are replaced with asterisks ("*") instead.

format_price($precision)

Returns a string containing "$number" formatted similarly to "format_number()", except that the decimal portion may have trailing zeroes added to make it be exactly "$precision" characters long, and the currency string will be prefixed.

If the "INT_CURR_SYMBOL" attribute of the object is the empty string, no currency will be added.

If "$precision" is not provided, the default of 2 will be used.

format_bytes($precision)

Returns a string containing "$number" formatted similarly to "format_number()", except that if the number is over 1024, it will be divided by 1024 and the value of KILO_SUFFIX appended to the end; or if it is over 1048576 (1024*1024), it will be divided by 1048576 and MEGA_SUFFIX appended to the end. Negative values will result in an error.

If "$precision" is not provided, the default of 2 will be used.

unformat_number

Converts a string as returned by "format_number()", "format_price()", or "format_picture()", and returns the corresponding value as a numeric scalar. Returns "undef" if the number does not contain any digits.
