integer $places optional 0

Decimal places to use.

string $decimals optional '.'

Decimal position string.

string $thousands optional ','

Thousands separator string.

addFormat()source public static

addFormat( string $formatName , array $options )

Add a currency format to the Number helper. Makes reusing currency formats easier.

$number->addFormat('NOK', array('before' => 'Kr. ')); ```

You can now use `NOK` as a shortform when formatting currency amounts.

$number->currency($value, 'NOK'); ```

Added formats are merged with the defaults defined in CakeNumber::$_currencyDefaults See CakeNumber::currency() for more information on the various options and their function.

Parameters

string $formatName

The format name to be used in the future.

array $options

The array of options for this format.

currency()source public static

currency( float $value , string $currency null , array $options array() )

Formats a number into a currency format.

Options

• wholeSymbol - The currency symbol to use for whole numbers, greater than 1, or less than -1.
• wholePosition - The position the whole symbol should be placed valid options are 'before' & 'after'.
• fractionSymbol - The currency symbol to use for fractional numbers.
• fractionPosition - The position the fraction symbol should be placed valid options are 'before' & 'after'.
• before - The currency symbol to place before whole numbers ie. '$'. before is an alias for wholeSymbol.
• after - The currency symbol to place after decimal numbers ie. 'c'. Set to boolean false to use no decimal symbol. eg. 0.35 => $0.35. after is an alias for fractionSymbol
• zero - The text to use for zero values, can be a string or a number. ie. 0, 'Free!'
• places - Number of decimal places to use. ie. 2
• fractionExponent - Fraction exponent of this specific currency. Defaults to 2.
• thousands - Thousands separator ie. ','
• decimals - Decimal separator symbol ie. '.'
• negative - Symbol for negative numbers. If equal to '()', the number will be wrapped with ( and )
• escape - Should the output be escaped for html special characters. The default value for this option is controlled by the currency settings. By default all currencies contain utf-8 symbols and don't need this changed. If you require non HTML encoded symbols you will need to update the settings with the correct bytes.
