Question

This function convert binary to decimal , Please can you code this function  differently

comp_bin is 1'scomplement function

---------------------------------

int binaire_dec(char bin[])
{
int i;
int valeur = 0;
int inverse;

char tab[NB_BITS];
strncpy(tab,bin,NB_BITS);
inverse = 0;

if(bin[NB_BITS-1] == '1')
{
comp_bin(tab);
inverse = 1;
}

for(i=0;i<NB_BITS;i++)
{
if(tab[i] == '1')
{
valeur+= (int)pow(2.0,i);
}
}
if(inverse)
{
valeur++;
valeur*=-1;
}
return valeur;
}

Explanation / Answer

Example 1 #include void binary(int); void main(void) { int number; cout > number; if (number < 0) cout digit = substring(number, i); > /* where, say, substring(11011, 2) returns 0 */ > /* but I'm not sure about this part */ > > if(digit == 1) > decimal += pow(2,i); > } > > return decimal; > }
