Floating point operations
On machines which support
the
IEEE Standard for Binary Floating Point Arithmetic
(ANSI/IEEE Standard 754-1985),
the C compiler uses the IEEE standard single-precision, double-precision
and extended-precision data types, operations, and conversions.
Library functions are provided for further IEEE support.
You will probably not need any special functions to use
floating point operations in your programs.
If you do, however,
you can find information about floating point support
in this topic.
NOTE:
For more information on how the C compilation system supports
the IEEE standard see
``IEEE requirements''.
This topic discusses the following:
-
the details of IEEE arithmetic
-
floating point exception handling
-
conversion between binary and decimal values
-
single-precision floating point operations
-
implicit precision of subexpressions
-
