Adding a zero in front of numbers and removing decimal place

[Steve_Kos]

Folks,

I am trying to take a known variable that is in the format "xx.xx" and do two things to it. The number range is from 7.00 to 24.99. I would like to add a zero to the begining and remove the decimal. Example: 3.66 would then be 0366 or 12.72 would be 1272. I have a feeling I am missing something so obvious that is right in my face. My goal is to take 2 variables and put them together in a string and send it out the serial port.

Any help would be greatly appreciated.

You can use sprintf to make a float into an ascii string. The output of
sprintf is put into a output buffer. You must declare the char array for
the output buffer before you use sprintf. Then you can edit the array
(with code designed by you) and do whatever you want with it.
After editing, you can transmit the string in the array through the serial port.

Or what about just multiplying the number by 100, storing the result in an integer (long), and using printf, with (say) %04ld.

PCM Programmer: Thank you for the advice, I will keep that in mind.

Ttelmah: Thanks, it worked like a champ. So simple, I knew it was staring me in the face.


Thanks!
