Hint:

Code: [Select]

( / 200. 1000. )Also look into the FLOAT function.

[JohnK]

Floating point / Decimal division.

Code - Auto/Visual Lisp: [Select]

1. (foreach mode '(1 2 3 4 5) (write-line (strcat "RTOS " (rtos mode) ": " (rtos (/ 100.0 2000.0) mode))))

EDIT: See ronjonp's post above mine.

Slightly more detail - when you provide two integers to the LISP math functions, it returns an integer.  If at least one of the arguments is a floating point, the return value is also floating point.
