- Expressions and evaluations
  The documentation provided here describes HCL Link functions and expressions. Functions and expressions are used to create component rules and map rules.
- Using functions
  A function is an expression that generates an output by performing a certain operation on one or more inputs.
- Syntax of a function
  The following is an example of a function:
- Function argument syntax
  Arguments typically have some restrictions on the expression used for that argument.

- General functions
  There are several general functions you can call from map rule to process input.

    The HEXTEXTTOSTREAM is the reverse of STREAMTOHEXTEXT.
  - INT
    You can use the INT function when you need only the integer portion of a number.
  - NUMBERTODATE
    You can use the NUMBERTODATE function to perform a calculation on a date.
  - NUMBERTOTEXT
    The NUMBERTOTEXT function converts a character number to a text item that looks like the original object.
  - PACK
    The PACK function converts an integer to a text item that can be interpreted as a packed decimal number.
  - PACKAGE
    The PACKAGE function converts a group or item object to a text item, including its initiator, terminator, and any delimiters it contains.
  - QUOTEDTOTEXT
    The QUOTEDTOTEXT decoding function converts a single (text or binary) data object in Quoted-Printable format to a single data object that represents the original text or binary object.
  - SERIESTOTEXT
    You can use the SERIESTOTEXT function to project your input data as a series and to interpret it as a text item for output.
  - STREAMTOHEXTEXT
    Use STREAMTOHEXTEXT to assign a character text value to a binary text stream item.
  - SYMBOL
    You can use SYMBOL to include a symbol in your output.
  - TEXTTOBASE64
    The TEXTTOBASE64 encoding function converts a text item to Base64 format.
  - TEXTTOBCD
    The TEXTTOBCD function converts a text item from decimal digits to BCD (Binary Coded Decimal) format.
  - TEXTTODATE
    The TEXTTODATE function converts text item from CCYYMMDD or YYMMDD format to a date.
  - TEXTTONUMBER
    Use TEXTTONUMBER to convert text to a number.
  - TEXTTOQUOTED
    The TEXTTOQUOTED encoding function converts a text or binary item to Quoted-Printable format.
  - TEXTTOTIME
    Use TEXTTOTIME when you want to convert an object defined as text that is in HHMM or HHMMSS presentation, to an item defined as time.
  - TIMETOTEXT
    You can use the TIMETOTEXT function to perform text concatenation.
  - TOBASETEN
    The TOBASETEN function converts a text item that can be interpreted as a number, using positional notation of the base specified, to a base 10 number.
  - TODATETIME
    The TODATETIME function converts a text string of a specified format to a date-time item.
  - TONUMBER
    The TONUMBER function converts a text string of a specified format to a number.
  - UNPACK
    You can use the UNPACK function to do arithmetic with a packed decimal number or to move a packed decimal value into a numeric item.
  - UNZONE
    You can use the UNZONE function to convert a text item that represents a zoned (signed) number to an integer.
  - ZONE
    Use ZONE to convert a number to a zoned (signed) number.
- Date/time functions
  You can use this function to perform various operations on date and time.
- Error handling functions
  You can use this function in evaluating the type of error during map execution.
- External interface functions
  You can use this function to retrieve data from a database from within in a map rule.
- Flow functions
  Use Flow functions to specify a value for each of the flow variables defined for a flow, and additionally, to alter an already specified value for a flow variable.
- Inspection functions
  You can use this function to test and inspect the object.
- Logical functions
  Logical functions provide a way to use logical conditions to display one of several values.
- Lookup and reference functions
  These function search operates by scanning the appropriate set of items in sequence, attempting to match the logical condition.
- Math and statistics functions
  Precede all MATHLIB functions with mathlib->
- Text functions
  These functions are used to convert the text item in a map rule.
- XML functions
  There are several XML functions that you can call from component rules and map rules to process input XML data.
- Custom functions
  From the Type Designer or Map Designer, you can create custom functions to call external libraries.
- Date and time format strings
  You can use the listed format strings for numbers, dates and times in functions such as the CURRENTDATETIME, FROMNUMBER, TONUMBER, FROMDATETIME, and TODATETIME.
- Number format strings
  You can create custom number formats by using the given format strings.
- RUN function return codes
  The RUN function return codes and messages might result when using the RUN function.
- Character set codes for CPACKAGE, CSERIESTOTEXT, and CTEXT
  The second argument of the CPACKAGE, CSERIESTOTEXT, and CTEXT functions specifies the character set of the output of the function. The value of the second argument (the character set of the object content), must be a valid character set code.

NUMBERTOTEXT

The NUMBERTOTEXT function converts a character number to a text item that looks like the original object.

You can use NUMBERTOTEXT when you need an object that is defined as a number converted to an object defined as text. This is useful when you need to concatenate text, however, the FROMNUMBER function provides greater flexibility in specifying the format of the resulting text item.

Syntax:: NUMBERTOTEXT (single-number-expression)
Meaning:: NUMBERTOTEXT (number_to_convert)
Returns:: A single text item

The resulting text looks like the input argument. The result is truncated, if necessary.

Examples

NUMBERTOTEXT (ROUND (1000 - 24.75, 3))
This example converts the result of the calculation (rounded to 3 decimal places) to text, resulting in 975.250.
NUMBERTOTEXT (PurchaseNumber)
This example converts PurchaseNumber from a number to text.
