Example

On some storage media, the number of bytes in a "gigabyte" of storage capacity may be 10^9 bytes, but the number of bytes in a file whose size is reported by some computer operating systems as "1 GB" may be 2^30 = 1073741824, which is a(3)=73741824 bytes larger. - Jon E. Schoenfield, Sep 07 2013
