TABLE 1-1:
1.5.1
MPLAB C32 C compiler stores multi-byte values in little-endian format. That is, the
least significant byte is stored at the lowest address.
For example, the 32-bit value 0x12345678 would be stored at address 0x100 as:
1.5.2
Integer values in MPLAB C32 C compiler are represented in 2's complement and vary
in size from 8 to 64 bits. These values are available in compiled code via limits.h.
1.5.3
By default, values of type plain char are signed values. This behavior is
implementation-defined by the C standard, and some environments
char value to be unsigned. The command line option -funsigned-char can be used
to set the default type to unsigned for a given translation unit.
1.5.4
MPLAB C32 C compiler uses the IEEE-754 floating-point format. Detail regarding the
implementation limits is available to a translation unit in float.h.
1.5.5
Pointers in MPLAB C32 C compiler are all 32 bits in size.
