We know that the double precision real number require a 64-bit representation.
This C program calculates the machine precision EPS and the mantissa of double precision real number. Actually, numbers represented in normalized double precision have the form

The 's' has 1 bit, the 'c' has 11 bits, and the 'f' which is called the mantissa has 52bits. By using this program, we found the machine precision EPS is .
The EPS is determined by the mantissa. In his program, '1' is divided by '2' because mantissa 'f' is

The a,b,c... are last 52bits of 64-bit representation. By using this program, we also found that the number of bits which mantissa has is 52.
