Line 11:

Similarly, the magnitude of the largest normal number in a format is given by

:''b''^''emax'' ×× (''b'' − ''b''^{1−''p''}),

where ''p'' is the precision of the format in [[numerical digit|digit]]s and ''emax'' is (−''emin'')+1.

Line 40:

For example, in the smallest decimal format, the range of positive normal numbers is 10^−95 through 9.999999 ×× 10⁹⁶.

Non-zero numbers smaller in magnitude than the smallest normal number are called [[denormal]] (or subnormal) numbers. Zero is neither normal nor subnormal.
