Internal Representation Of Numerical Types

Go Up to Constants Overview Index

Integers

Integer values have the following internal representation in the architecture of the Intel Pentium family of microprocessors:

Error creating thumbnail: Unable to save thumbnail to destination

Floating-point types

Floating-point values have the following internal representation in the architecture of the Intel Pentium family of microprocessors:

Error creating thumbnail: Unable to save thumbnail to destination

Here we use the following terms:

s	Sign bit (0 = positive, 1 = negative)
i	Position of implicit binary point
1	Integer bit of significance. It is stored explicitly in long double and it is used implicitly in float and double
Biased exponent (normalized values)	127 (7F) for float 1,023 (3FF) for double 16,383 (3FFF) for long double
