## convert bcd to decimal

Hello

In assembly you can use an instruction that is DA that means Decimal adjust.

## Re: how to convert binary to BCD or decimal in assembly

Hey, I found this code was exactly what I needed.

Converts 16-Bit (2 Registers) To Unpacked BCD Decimal.

Works on the 18FXXX Series PIC

Integrated this code into my own project as a function call and works like a hot damn. Hope this helps.
