Table 10.18 shows the types of values represented as floating-point numbers.
Table 10.18 Types of Values Represented as Floating-Point Numbers
Note: Denormalized numbers are floating-point numbers of small absolute values that are outside
Mantissa

Other than 0
(c)
In addition to the normal real numbers, floating-point numbers can also represent values
such as infinity. The following describes the types of values represented by floating-point
numbers.
i. Normalized number
ii. Denormalized number
iii. Zero
iv. Infinity
v. Not-a-number
the range that can be represented by normalized numbers. There are fewer valid digits in a
denormalized number than in a normalized number. Therefore, if the result or intermediate
result of a calculation is a denormalized number, the number of valid digits in the result
cannot be guaranteed.
Types of represented values of floating-point number
When the exponent is not 0 or not all bits are 1. Represents a normal real value.
When the exponent is 0 and the mantissa is other than 0. Represents a real value having
a small absolute value.
When the exponent and mantissa are 0. Represents the value 0.0.
When all bits of the exponent are 1 and the mantissa is 0. Represents infinity.
When all bits of the exponents are 1 and the mantissa is other than 0. Represents the
result of operation such as "0.0/0.0", " / ", or " - ", which does not correspond to a
number or infinity.
