Decimals are stripped from DM calculations. Apparently you can use FTOA to get the decimals:Decimal Calculations in DM

There is a new setting called DMPRECISION which I have not used that you might find useful.
quote:
DMPRECISION
The DMPRECISION parameter specifies numeric precision in Dialogue Manager -SET commands.

Without this setting, results of numeric calculations are returned as integer numbers, although the calculations themselves employ double-precision arithmetic. To return a number with decimal precision without this setting, you have to enter the calculation as input into subroutine FTOA, where you can specify the number of decimal places returned.

The syntax is:

SET DMPRECISION = {OFF|n}
where:

OFF
Specifies truncation without rounding after the decimal point. OFF is the default value

n
Is a positive number from 0-9, indicating the point of rounding. Note that n=0 results in a rounded integer value.

Thanks Ginny. SET DMPRECISION Command available from 7.6.0 onwards.
Here is a code snippet.

-SET &ECHO=ALL;
SET DMPRECISION=0
-RUN
-SET &LUCY_0 = 5/3;
-TYPE &LUCY_0 
SET DMPRECISION=1
-RUN
-SET &LUCY_1 = 5/3;
-TYPE &LUCY_1 
SET DMPRECISION=2
-RUN
-SET &LUCY_2 = 5/3;
-TYPE &LUCY_2 
SET DMPRECISION=3
-RUN
-SET &LUCY_3 = 5/3;
-TYPE &LUCY_3


Note: -RUN after each DMPRESISION set command.
