string Function

The string representation of the given expression.

The example below retrieves the decimal portion of a real number.

1. We use the string function to convert the real number to a string
2. We then use the string.split function to split the string around the decimal point
3. Finally, we use the array.get_at function to retrieve the second element (at index 1, the decimal portion of the original number)

$piStr = string(3.1416);
$piSplit = string.split($piStr, ".");
PRINT array.get_at($piSplit, 1); /* 1416 */
