## binary values

The following table shows the decimal values of binary numbers. Just as the largest value in a group of decimal digits is expressed as all 9's, the largest value in a group of binary digits is all 1's. A decimal digit provides 10 distinct values (0 through 9), but a binary digit has only two (0 or 1). See NIST binary and space/time.
