Define arbitrary set of units and split up a number into those units. The module includes preset sets of units for some measures

`denominate`

say denominate 1234567; say denominate 23*3600 + 54*60 + 50, :1precision; denominate 449, :units( foo => 3,=> 32, 'ber' ); denominate 1234567, :hash; denominate 1234567, :array; # Valid unit sets: info info-1024 length length-imperial length-mm time # volume volume-imperial weight weight-imperial denominate 21212121, :set ;

**Takes** one mandatory positional argumentâ€”the number to denominateâ€”and
several optional named arguments that affect how the number is denominated
and what format the denomination is returned in. See `hash`

and `array`

arguments to modify the default `string`

return value. The named arguments are as follows:

`array`

# [ # {:denomination(7), :plural("weeks"), :singular("week"), :value(2) }, # {:denomination(24), :plural("days"), :singular("day"), :value(0) }, # {:denomination(60), :plural("hours"), :singular("hour"), :value(6) }, # {:denomination(60), :plural("minutes"), :singular("minute"), :value(56)}, # {:denomination(1), :plural("seconds"), :singular("second"), :value(7) } #] say (denominate 1234567, :array).perl;

Boolean. **Defaults to** `False`

. When `True`

, `denominate`

will return denominations as an array of hashes. Each hash represents a single
unit and has the following keys. The array will always contain each
`unit`

, ordered from largest to smallest.

`denomination`

How many of the next smaller unit fits into this unit. This value is `1`

for
the smallest unit in the set.

`plural`

The plural name of the unit.

`singular`

The singular name of the unit.

`value`

The actual value of this unit.

`hash`

# {:hours(6), :minutes(56), :seconds(7), :weeks(2)} say (denominate 1234567, :hash).perl;

Boolen. **Defaults to** `False`

. When `True`

, `denominate`

will return denominations as a hash. The keys will be the **singular** names of
units and values will be the values of those units. **Note:** units whose values
are zero will not be included.

`precision`

# 23 hours, 54 minutes, and 50 seconds say denominate 23*3600 + 54*60 + 50; # 1 day say denominate 23*3600 + 54*60 + 50, :1precision; # 23 hours and 55 minutes say denominate 23*3600 + 54*60 + 50, :2precision;

**Takes** positive integers as the value. **Defaults to** the number of
`units`

given (or the number of units in the `set`

).
Specifies how many, at most, units to include in the output. Rounding will
be performed if needed. When output mode is set to `array`

, all units
will be present, but at most `precision`

units will have non-zero
values.

`set`

# 2 weeks, 6 hours, 56 minutes, and 7 seconds say denominate 1234567; # 21 tonnes, 212 kilograms, and 121 grams say denominate 21212121, :set; # This script's size is 284 bytes say "This script's size is " ~ denominate $*PROGRAM-NAME.IO.s, :set ;

Loads a pre-defined set of `units`

to use for denominations.
Has effect only when`units`

argument is not specified.
**Defaults to** `time`

. **Takes** the name of one of the predefined
unit sets, which are as follows (see description of `units`

argument,
if the meaning of values is not clear):

`info`

yottabyte => 1000, zettabyte => 1000, exabyte => 1000, petabyte => 1000, terabyte => 1000, gigabyte => 1000, megabyte => 1000, kilobyte => 1000, 'byte'

Units of information.

`info-1024`

yobibyte => 1024, zebibyte => 1024, exbibyte => 1024, pebibyte => 1024, tebibyte => 1024, gibibyte => 1024, mebibyte => 1024, kibibyte => 1024, 'byte'

Units of information (multiples of 1024).

`length`

'light year' => 9_460_730_472.5808, kilometer => 1000, 'meter'

Units of length (large only).

`length-imperial`

mile => 1760, yard => 3,=> 12,

Units of length (Imperial).

`length-mm`

'light year' => 9_460_730_472.5808, kilometer => 1000, meter => 100, centimeter => 10, 'millimeter'

Units of length (includes smaller units).

`time`

week => 7, day => 24, hour => 60, minute => 60, 'second'

Units of time.

`volume`

Liter => 1000, 'milliliter'

Units of volume.

`volume-imperial`

gallon => 4, quart => 2, pint => 20, 'fluid ounce'

Units of volume (Imperial).

`weight`

tonne => 1000, kilogram => 1000, 'gram'

Units of weight.

`weight-imperial`

ton => 160, stone => 14, pound => 16, 'ounce'

Units of weight (Imperial).

`string`

# 2 weeks, 6 hours, 56 minutes, and 7 seconds say denominate 1234567;

Boolean. Has effect only when `hash`

and `array`

arguments
are `False`

(that's the default). **Defaults to** `True`

. When `True`

,
`denominate`

will return its output as a string. Units
whose values are zero won't be included, unless the number to denominate is
`0`

, in which case the smallest available unit will be present in the
string (set to `0`

).

`units`

# 4 foos, 2 boors, and 1 ber say denominate 449, :units( foo => 3,=> 32, 'ber' ); # These two are the same: denominate 42, :units( day => 24, hour => 60, minute => 60, 'second' ); denominate 42, :units( => 24, => 60, => 60, );

Specifies units to use for denominations. These can be set to one of the
presets using the `set`

argument. Takes a list of pairs where the
key is the name of the unit and the value is the number of the next smaller
unit that fits into this unit. The name is a list of singular and plural name
of the unit. If the name is set to a string, the plural name will be derived
by appending `s`

to the singular unit name. The smallest unit is specified
simply as a string indicating its name (or as a list of singular/plural
strings).
