The format implementation was completely redone in Jess 6.1a2. The old
format had a lot of problems, and this new one is both better and more
standards-compliant. It's based on some public-domain code from Sun.
The error message that you get from the above is something like:
Jess reported an error in routine format
while executing (format nil "%04d" (* (fetch TopPad) 1.0E-4)).
Message: Bad format string %04d.
Program text: ( format nil "%04d" ( * (fetch TopPad) 1.0E-4 ) ) at line 1.
Nested exception is:
Cannot format a double with a format using a d conversion character.
The last line of the message is a fairly clear explanation: "d" is a
format conversion character for integers, not floats. If you use "d"
to print a double in the C language, you'll get garbage. Jess is just
making this explicit.
If you want to print the number as an integer in a four-digit field,
then convert it to an integer using the (integer) function first:
(format nil "%04d" (integer ( * (fetch TopPad) 1.0E-4)))
