Well, you could use these macros to covert to decimal, perform the math and convert back to BCD:<br />

Thanks, but I need BCD because long or doudle are not accurate enought for my program (simple finance calculs but with lots of digits).

A long on a 32 bit machine is 64 bits, which supports numbers up to 18 digits. That's larger than the GDP of any country I can think of. That should be sufficient for any financial calculations.<br />

I working on PDA (some are 16bits). <br />
But 18 digits is not enought, I need numbers like<br />
1 000 000.000 &nbsp;(10 digits). In some calculs I have to multiply two numbers, so I need 20 digits.<br />
<br />
I need exact results even the last digits.<br />

Looking for BCD source code

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
