Feet Plus Inch Calculator

[Wonder-Man]

Hi All

I'm look for a macro or lips to create Feet-Inch calculator (specially adding feet-inch to feet-inch and other math operations). working in architectural design requires in many occasions adding and subtraction feet-inch calculations

Thanks

This is an excellent feet/inch calculator program but it is not free.
I'd bet that LeeMac could make one just as good during his lunch break.

Use the distof function to convert everything to decimal, perform the arithmetic, then use the rtos function to convert back to feet/inches.

Quick example:

(defun c:add ( / _getnumber tot num )

    (defun _getnumber ( msg / str num )
        (while (not (or (eq "" (setq str (getstring t msg))) (setq num (distof str))))
            (princ "\nPlease enter a number.")
        )
        num
    )

    (if (setq tot (_getnumber "\nSpecify Amount: "))
        (while (setq num (_getnumber "\nSpecify Amount to Add <Exit>: "))
            (princ (strcat "Total: " (rtos (setq tot (+ num tot)))))
        )
    )
    (princ)
)

Or just buy the right calculator (since you'll be doing this addition quite often).

Have you decided which log-in you wanted to keep?

Enter QC in the command line to open the "Quick Calculator"
Make sure that your units are set in your drawing accordingly...
The trick for using fractional inches that I have found is to use the minus sign as a spacer between the whole inch and the fractional inch:
2 1/2" = 2-1/2"
Others have had success using a regular space, but I find using the minus sign works...

I have one of these, but the more expensive one for the Pipe Fitting trade. Same company. I love it, and it goes with me everywhere my laptop goes.

Is it so complicated to be written in Lisp and Dcl files?
