BCD to decimal conversion in C program

[learnc009]

I am working on a project using microchip PIC16F946, for RF controller. The current code have a working private ID code in binary. The LCD has 4 digits And 4 binary digits can only handle a miax of 16 IC code (1111). Now I want to increade the code to random number or as many ID number as need. So I want to use these 4 bidits as 4 BCD. And convert these 4 BCD digits into 16 pure binary or into decimal number. As you know 1 BCD represents 0 to 9 in decimal oe 1 BCD represnts 8 binary bits.

Anyone, please help me to write a working code to convert 4 BCD digits to 16 Binary or decimal.

Hope some expertise, samart people out there will reach out and help.

Thanks.

There is no need to convert BCD to decimal, because BCD is already decimal, where each digit is from 0 to 9, encoded by 4 binary digits. Converting to binary will be something like this

for(i=0;i<4;i++)
{
result *= 10;
result += bcd[i];
}
