What I was really looking for was a solution that would allow for a binary
number encoded in BCD to be converted to decimal. Eg

10000 11001 = 1 3
Do you mean 0001 0011 -> 1 3?

How is your BCD number held, as a byte array or what?

How do you want the decimal equivalent, as a string, int, long, double
or what?

Here is some example code to convert BCD held in a big-endian byte
array to a long:

long BCD2Long(byte source) {
long result = 0;
foreach (byte b in source) {
int hi = b >> 4;
int lo = b & 0x0F;
result *= 10;
result += hi;
result *= 10;
result += lo;
}
return result;
}
