The internal representation format consists of the following parts:
Floating-point numbers handled by this compiler are internally represented in the standard
IEEE format. This section outlines the internal representation of floating-point numbers in the
IEEE format.
(a) Format for internal representation
(b) Structure of internal representation
float types are represented in the IEEE single-precision (32-bit) format, while double types
and long double types are represented in the IEEE double-precision (64-bit) format.
Figure 10.1 shows the structure of the internal representation of float, double, and long
double types.
