Hello,

Where can I find documentation for the built in functions for report writer?

I have an issue with the toString() function. It returns a string value "99.0" for an integer variable with value of 99. How can I get it to return "99" without the training ".0".

Thank you

Joe Miller

Thank you for your reply,

I have found the toString() function documentation. Unfortunately it doesn't document its return value or any method of controlling its return value.

I don't understand why this function is returning a representation of a float value when the value being converted is an integer. Can you provide a method for properly converting and displaying an integer value?

Thank You

Try the function Numeric.format(String formatString) which is compatible with the 4GL FORMAT string. As an example consider the expression (12.34).format("###") which yields the String "12".
