    Does anyone know of a command that will extract the last digit from a number.

    For example, if i have the number 293320.021384, is there a command that will return the 4 from that number?

    Thanks for any help...

    (setq Str_Real (rtos 293320.021384 2 6))
    (setq Last_Num (substr Str_Real (strlen Str_Real)))

    This assumes you know the number of decimal places in the number, otherwise
    the code will be a lot longer.

    thanks, but i decided to convert it to a string and work with it that way.

    Hi clay_p
    try this:

    (setq long-num 293320.021384)
    (setq num-as-string (rtos long-num 2 17))
    (print (substr num-as-string (strlen num-as-string)))

    Regards
    Dieter
