4.2 Grammar of C Source
The C Compiler gcc33 included in this package is the GNU C Compiler (ver. 2.7.2) under ANSI C standards.
Since everything except the asm function of this compiler conforms to standard specifications, make sure C
sources are created according to ANSI C standards. If you want information about the syntax, please refer to
ANSI C textbooks generally available on the market.
4.2.1 Data Type
The gcc33 supports all data types under ANSI C. The size of each data type (in bytes) and the effective range of
values that can be expressed are listed in Table 4.2.1.1.
The float and double types conform to the IEEE standard format.
4.2.2 Library Functions and Header Files
This package contains an ANSI standard library and an emulation library for calculating floating-point numbers
and the remainders of divided integral numbers.
The header files in the "include" directory contain library function declarations and macro definitions. When
using a library function, include the header file that contains its declaration by using the "#include" instruction.
The table below shows the relationship between the types of library files and the header files.
