The String function changes the datatype of the
parameter to string.
Parameter: datatype
Any string, boolean,
date, or numeric datatype. This can come from a source node, the result
of another function, or a value that you specify.
Returns: string
The
result of changing the parameter to string. The conversion rules depend
on the datatype of the parameter:
- For boolean datatypes, returns the string true or false
- For date or time datatypes, returns the date or time as a string
in the specific format for that datatype, such as ‘2003-01-20T05:00:00'
for a datetime datatype.
- For number datatypes, this returns:
- ‘NaN' if the value is NaN (not a number)
- ‘0' if the value is positive or negative zero.
- ‘Infinity' or ‘-Infinity' if the value is positive or
negative infinity (respectively).
- The corresponding numeral, with a minus sign if negative and no
leading zeroes. Decimal values have at least one numeral before the
decimal point and as many decimal places as needed.
