formatNumber(value, picture, language, letterValue, ordchar, zeroPadding, groupingSeparator, groupingSize) → {XsString}

Returns a formatted number value based on the picture argument. The difference between this function and the W3C standards fn:format-number function is that this function imitates the XSLT xsl:number instruction, which has richer formatting options than the fn:format-number function. This function can be used for spelled-out and ordinal numbering in many languages. This function is available in XSLT as well as in all dialects of XQuery and Server-Side JavaScript. Provides a client interface to a server function. See xdmp.formatNumber
Parameters:
Name Type Argument Description
value XsNumeric <optional>
 The given numeric $value that needs to be formatted.
picture XsString <optional>
 The desired string representation of the given numeric $value. The picture string is a sequence of characters, in which the characters represent variables such as, decimal-separator-sign, grouping-sign, zero-digit-sign, digit-sign, pattern-separator, percent sign and per-mille-sign. For details on the picture string, see http://www.w3.org/TR/xslt20/#date-picture-string. Unlike fn:format-number(), here the picture string allows spelled-out (uppercase, lowercase and Capitalcase) formatting.
language XsString <optional>
 The desired language for string representation of the numeric $value. An empty sequence must be passed in even if a user doesn't want to specifiy this argument.
letterValue XsString <optional>
 Same as letter-value attribute in xsl:number. This argument is ignored during formatting as of now. It may be used in future. An empty sequence must be passed in even if a user doesn't want to specifiy this argument.
ordchar XsString <optional>
 If $ordchar is "yes" then ordinal numbering is attempted. If this is any other string, including an empty string, then cardinal numbering is generated. An empty sequence must be passed in even if a user doesn't want to specifiy this argument.
zeroPadding XsString <optional>
 Value of $zero-padding is used to pad integer part of a number on the left and fractional part on the right, if needed. An empty sequence must be passed in even if a user doesn't want to specifiy this argument.
groupingSeparator XsString <optional>
 Value of $grouping-separator is a character, used to groups of digits, especially useful in making long sequence of digits more readable. For example, 10,000,000- here "," is used as a separator after each group of three digits. An empty sequence must be passed in even if a user doesn't want to specify this argument.
groupingSize XsInteger <optional>
 Represents size of the group, i.e. the number of digits before after which grouping separator is inserted. An empty sequence must be passed in even if a user doesn't want to specifiy this argument.
