Adding zero

I working on a binary program that requires strings of
zeros, I am able to get to work as long as the first digit
is a one, however when it is broken up into different bits,
the first digit is often a zero, and the program can't
continue to add to the zero, while keeping the zero in the
first location. (ie, 010 ends up as 10) is there anyway of
keeping that zero as a place holder?

How are you storing the values? From what you write, it
almost sounds as if you are trying to fake a bit stream
using base 10.

If you are using dec2bin() then consider using bitget() instead.[color=darkred]

ans =

10101101[color=darkred]

ans =

Columns 1 through 13

0 0 0 0 0 0 0 0 1 0 1 0 1

Columns 14 through 16

1 0 1

Note that bitget returns a numeric array where dec2bin returns
a character string.
