Line 74:

values for the binary formats. Note also that the "00", "01", or "10" bits are part of the exponent field.

Note that the leading bits of the significand field do ''not'' encode the most significant decimal digit; they are simply part of a larger pure-binary number. For example, a significand of {{gaps|8|000|000|000|000|000}} is encoded as binary {{gaps|1110111|0001101011|1111010100|1001100011|0100000000|0000000000}}, with the leading 4 bits encoding 7; the first significand which requires a 54th bit is 2⁵³ = {{gaps|9|007|199|254|740|992}}.

In the above cases, the value represented is
