number to bcd

Got to be an easier way. I want to turn a variable number into a BCD number
for seven segment displays. I'm not using the decoder chip. What
suggestions can you guys offer to get a number 0-9999 into a 4 byte string.
Currently I start by dividing by 1000 to get first digit, then divide the
remainder by 100 to get the second digit etc.
I this what the DIG modifier is for?

Hi Chris,
Shield the cable. Near the Stamp, run it through an RFI bead (the
fat thing you often see on cables).

Sorry, I'm making an rpm gauge for my lathe and mill.
It's not rally a stamp question cause I'm gonna make the final design using
a pic, but Pic Basic Pro is almost Stamp.
What I want to do it take the RPM counts input and convert that to a BCD
string to display on 7-segs. SO I need it in bcd byte format. All serial
output routines convert it for you using the "Dec" modifier but I need to
use the bytes elsewhere in the program.

Just go to Calculator - Scientific. Enter the decimal number then click on

is mechanically limited to 10 positions. (0 thru 9). I have the 2 BCD
digits feeding a parallel to serial chip converting them into a 8 bit
variable called BCD for example. Simply break out the high nib and low nib
of BCD. For example the two switches are set to 6 4:
BCD variable gets set to the following, (binary), 01100100. The upper
nib is 0110 (6 dec) and the lower is 0100 (dec 4). From here you can do
what ever you want with the values..

Looks like my documentation may be old. Where can I find more information on
the DIG command?

each digit into individual variables. I then used:
var1 * 10 + var2 * 10 + var3 * 10 + var4 = newVar 'to get it all
in one variable.
I guess that only uses two lines of code? I was reading in a 4 digit
number and outputting it to a lcd and led display converting it to xx.xx
format.
Great suggestion but then I would spend all my time at the calculator not
machining parts.
Sorry, I'm making an rpm gauge for my lathe and mill.

binary operators. You can download the latest manual -- free -- from our web
site. If you want a printed version, they're currently on sale. Don't delay
though, sales don't last forever.

wiring or a PCB, just get a LCD screen. Can get a 2 line x 24 char
for $10. The serial LCDs would be even easier, but at $40 it gets
pricey.
I'm woirking on a DRO (with LCD) for my mill from a hacked digital
caliper.(lathe really doesn't need one for my uses) Though its done
with a 'normal' PIC since I need SPI and to custom configure the SPI.
