Wanted to share this snippet of code which I used to display a decimal numbers binary representation. It is quite self explanatory and easy to understand.
/**
* Turns a decimal value to its binary representation
*/
char* dec2binWzerofill(unsigned long Dec, unsigned int bitLength){
return dec2binWcharfill(Dec, bitLength, '0');
}
char* dec2binWcharfill(unsigned long Dec, unsigned int bitLength, char fill){
static char bin[64];
unsigned int i=0;
unsigned int j;
while (Dec > 0) {
bin[32+i++] = ((Dec & 1) > 0) ? '1' : fill;
Dec = Dec >> 1;
}
for ( j = 0; j< bitLength; j++) {
if (j >= bitLength - i) {
bin[j] = bin[ 31 + i - (j - (bitLength - i)) ];
}else {
bin[j] = fill;
}
}
bin[bitLength] = ' ';
return bin;
}
