Fanuc karel leading zeros

    Hello everyone. I have a problem with fanuc data with Real type. For my task i need to convert my cartesian robot position into string and send it to external device. But in Fanuc system, if data is in range from -1 to 1, then there is no leading zeros. So data such as 0.234 looks like .234. So because of there is no leading zeros external device can't parse robot position. To convert position i use CURPOS(0,0) to get current position and then for each coordiante CNV_REAL_STR routine to convert from real to string.

    I wrote a simple routine that check, if coordinate is between -1 and 1 and add leading zero to start of converted coordinate, but maybe there is standart buildin karel routine to keep leading zeros active, or maybe system variable to include leading zeros?

    Approved the thread.

    Any chance you could post some code. I am doing the same at the minute but I am having trouble converting each position from a REAL to a STRING using CNV_REAL_STR when I look at the strings in roboguide I just get a bunch of asterisk *****

    Hi

    when using "CNV_REAL_STR"

    check the length and num_digits argument!

    Syntax : CNV_REAL_STR(source, length, num_digits, target)

    Details:

    • source is the REAL value to be formatted.
    • length specifies the minimum length of the target . The actual length of target may be greater if
    required to contain the contents of source and at least one leading blank.
    • num_digits specifies the number of digits displayed to the right of the decimal point. If num_digits
    is a negative number, source will be formatted in scientific notation (where the ABS( num_digits )
    represents the number of digits to the right of the decimal point.) If num_digits is 0, the decimal
    point is suppressed.
    • If length or num_digits are invalid, target is returned uninitialized.
    • If the declared length of target is not large enough to contain source with one leading blank, target is returned with one leading blank and the rest of its declared length filled with ``*''s (asterisks).
