What is the problem?

What is the type of the malloced buffer,is it char?

Is it something like:

char *buf;
buf=(char*)malloc(20*sizeof(char));
strcpy(buf,"1100110");
//Now you need the decimal value of 1100110 in a float.Is this what you need?
free(buf);

You need to retrieve only 1 number from the malloced data or more than one?

See this,it might help:

Ok.So you have the binary numbers stored as floats.Right?

Something like:

float *buf;
buf=(float*)malloc(20*sizeof(float));
buf[0]=11001.11;
buf[1]=10010.11;
.
.
//And you need the decimal values of these individual elements,right?
free(buf);
